Is it possible to cut a roller blind

How to neatly trim the curtains of the thread to the desired length

How to trim curtain threads exactly

The standard curtain length is up to three meters. Usually there is a need to shorten the product. It is not necessary to go to the atelier and pay the master for the work. At home, you can easily cut curtains-threads, both in length and in width of the product. What is required for this, consider below:

How to cut square roller blinds?

• Remember that this procedure cannot be performed in a horizontal position. The threads can get tangled, and, as a result, it will not be possible to cut them exactly. the product will be damaged. To avoid mistakes, hang the curtains on the cornice, as they will hang after trimming.
• The curtains should hang for three days. This is necessary in order for them to stretch out. This is the only way to ensure that the threads are strictly vertical and parallel to each other. This will create the most graceful effect.
• Check carefully that the fabric is perfectly flat. Only then proceed with pruning.
• Take some tailor’s scissors and trim the curtains neatly.
• Thread curtains made of quality material do not require additional processing.

To simplify the process, try pressing the ends of the threads to the floor with a piece of cardboard.

Scissors for work must be sharpened, otherwise they will “chew” the threads and can damage the appearance of the product.

Now that you know how to cut filament curtains without problems, feel free to purchase them, because, without exaggeration, they can adequately decorate any room.

How to trim curtains-threads curly

Above, we described in detail the procedure for horizontal trimming of curtains. But the curtains at the bottom don’t have to be straight. Curly trimming is popular. Do not be afraid and think that only a professional seamstress can do this. You will completely cope with this on your own, and we will tell you how to shorten the muslin figured.

The actions for curly cropping are, in general, similar to the instructions described above:

• Hang the curtains for exactly a few days. Above the curtains have a wide ribbon-border. For it, you can hang the curtain on a regular cornice with clothespins. There is an alternative: sew on the curtain tape for the hooks and hang the curtain using the hooks on the cornice.
• When they are perfectly straight, you can start cutting.
• Make a stencil out of thick paper. You can use a cardboard box as a material. The stencil is needed to ensure that the cut line of the cut is clearly tailored to your wishes.
• Attach the stencil to the curtains. Better ask someone for help. This makes it easier for you to do your work.
• Trim the excess length carefully. Be careful, don’t rush.

On the Internet, the question of how to process the ends of the threads is often encountered. We wrote above that in most cases this is not required. However, any situation can arise. Here are the most convenient ways to process a slice:

• beads can be sewn onto the end of the thread, or you can tie it into a small knot;
• If the item is made of synthetic fabric, try setting it on fire with a lighter. Check this method first on a small piece of fabric so as not to spoil the product;
• another option: touch up the ends of the threads with transparent nail polish, it will not let them bloom.

It should be understood that these methods do not always look aesthetically pleasing and can spoil the attractiveness of the muslin curtain. Before using them, think carefully whether it is really so necessary.

How to shorten the length

Most often, adjustment of roller blinds along the length is not required, since it is enough just not to unwind the canvas to its full length. But if you are a perfectionist and it is extremely important for you that the blinds are of the right size, then follow these instructions:

• Hang the curtains, lower the canvas, wait for it to fully unfold and lie down neatly, then take measurements.
• Mark where you want to crop the canvas.
• Remove roller blinds, spread them out on a horizontal surface.
• Remove the weight from the bottom edge.
• Add an allowance of 40-50 mm to the measured length to create a new “” for the weight.
• Cut the fabric.
• Place a canvas underneath the curtain and sew a “” for the weighting agent, insert it.
• Hang the curtain on the window.

If the length of the “excess” fabric is not too long, then trimming can be dispensed with. It is enough to make a double fold of the fabric, with which you can hide up to 30 cm of fabric. This option of shortening the roller blind is much easier and faster.

Types and sizes of roller blinds

Manufacturers offer a huge assortment of roller blinds, among which you can choose products of any size and for any window. But still, sometimes there are situations when the roller blinds offered by the seller do not have the right size for your windows. This usually happens if windows of non-standard sizes were laid in the building project, or the dimensional grid of the roller blinds you liked is limited and does not contain a model suitable for you.

In this case, there are two ways out of the situation:

• Order custom tailoring of roller blinds. The most convenient solution to the problem. With minimal effort on your part and without any hassle, you will receive roller blinds that will fully meet your expectations and the dimensions of the window opening. But this method has a significant drawback. high cost of the finished product.
• Buy a sun protection system as close as possible to the desired size, but slightly larger than it, and cut the roller blind yourself. Having decided to do this, you will need to make some effort and spend a little personal time, but the curtains will cost you inexpensively.

The following types of roller blinds are on sale:

Their feature. an open shaft that is not protected by anything. Such blinds are inexpensive, take up little space, and can be mounted above a window opening or on each window sash. Their maximum web width is 1.8 m, height. 2 m.

Roller blinds of this type are equipped with a plastic box that hides the rotating shaft and protects it and the wound fabric from dirt and accidental damage. Another difference between them. small size. The width of the web starts from 0.7 m, the length does not exceed 2.2 m.

Available in lengths up to 4.5 m and widths up to 3.5 m, these roller blinds are perfect for large window openings such as panoramic windows or wide windows in office buildings.

Roof roller blinds are designed to be installed on sloped windows. For a snug fit to them, they are specially equipped with side guides that hold the canvas along the window sashes. Their height. no more than 2 m, width. not less than 0.7 m.

Doesn’t fit the size. How to cut a roller blind with your own hands?

If you cannot find blinds of suitable dimensions in any way and do not want to contact the master for individual tailoring, as it is very expensive, then you can solve this problem on your own by cutting the roller blinds to the required size.

How to cut a roller blind with your own hands?

Roller blinds. one of the most common design options for a window opening. They serve both decorative and practical functions. This compact and stylish sun protection system fits perfectly into almost any room, reliably protects from the sun’s rays, easy to use, easy to operate.

Blinds are a construction of fabric, a rotating shaft and a special mechanism that winds the fabric on a roller. Unlike the blinds, the canvas is solid, and there are no gaps, due to which, when the curtains are lowered, complete darkness in the room is ensured. Compared to the usual curtains, roller blinds are more compact, weigh less, can be rolled up, are easier to clean, since due to special impregnations they do not collect dust and are less dirty.

How to cut the roller blind to the width

Cutting roller blinds in width is more difficult and requires more care. Preliminary preparation and measurement is done in the same way as described above. After all measurements are made and the fabric is marked, you can proceed to adjusting the canvas to the desired size. The scheme of work is as follows:

• Lay out the curtains on a flat surface, disassemble into components (take out the shaft and weighting agent) and unfold the fabric.
• Cut the shaft to the required width. Please note that its width should be 8-10 mm wider than the width of the canvas. It is better to cut with a hacksaw. After trimming the edges, be sure to sandpaper or file so that there are no chipping on which the fabric can catch.
• Cut off the weighting agent (it should be 10-15 mm narrower than the roller blinds).
• Assemble the curtain back into a single structure and hang it on the window.

It should be remembered that cutting the roller blinds will immediately void the warranty on them. Therefore, it is worth starting this operation if there are no other options anymore or the guarantee is not too important for you.

Installing brackets on a frame or on a wall

Determine where the first bracket will be located and mark the locations for the holes. If you are mounting the bracket to a window frame, drill the holes with a thin wood drill bit (2.5 mm).

If the bracket is wall-mounted, use a 6 mm brick drill and dowels of the same size. Install the first bracket and lightly tighten the screws.

Align the shaft horizontally using a long piece of wood and a building spirit. Then mark the points for drilling holes for the second bracket.

Fastening the curtain to the shaft

Remove the protective film from the self-adhesive strip of the shaft. The curtain should be wrapped around the shaft and unfold from the window side.

Check which side the control mechanism is located on. The blade must be fixed on the shaft strictly horizontally, otherwise it will unfold at an angle! Fold over 5 cm of the top side of the fabric so that a crease forms.

Place the shaft in the fold with the adhesive strip facing up. Use both hands to roll the shaft towards the top of the blade.

Then roll the curtain ¾ of its length and insert the bottom rail into the hole on the curtain. The curtain is now ready for installation.

Measurement of width

If you want to hang the curtain from the window frame, measure the width of the curtain along with the brackets. Allow 5mm clearance on each side of the frame to facilitate installation of brackets.

Recommendations for how easy it is to shorten vertical blinds

Blinds are a comfortable modern decor, ideas for home interior decoration using stripes are always original. Blinds slats are made of various materials: fabric, bamboo, plastic.

To reduce their number, we lay the lamella base on the floor, remove the side cover from the side of the lifting mechanism, unscrew the fixing bolts. Remove excess lamellas, shorten the length of the cords.

Trimming of fabric slats in width is practiced, each is uncoupled from the slider, tucked in or cut off with a cut.

With this adjustment, the number of lamellas remains the same, and their format changes. The cornice is sawn from the side opposite to the reverse mechanism.

How to trim yourself?

Roller blinds, as a rule, are cut in the event that it is necessary to change the decor of the room or if they do not correspond to the size of the window openings, which often happens when you move and change your place of residence. Any hostess can shorten the rolled canvases.

First, the fabric should be hung on the cornice, after it straightens out and takes its final shape, measurements are taken. In this case, the decorative processing of the product below will depend on the type of fabric.

In the event that the curtains are sewn from silk or organza, then markings cannot be applied to them, otherwise traces may remain. To prevent this from happening, use universal adhesive strips.

They are pre-ironed with an iron, and then the canvas and the bent piece are fastened. It is necessary to iron the strips through cheesecloth, laying the fabric on a soft towel.

The edges of the roller blinds can also be finished with an edging, which is a fabric tape. It is first fixed with pins, then stuck in. In this case, it is not necessary to shorten the curtains from the bottom, there is a way to reduce the length from the top edge.

Regardless of the type of trimming, you will need tailor’s soap, scissors, iron, threads, needles and a measuring tape for work.

The shortening process itself consists of several stages.

• The edge is cut first. This should be done carefully, otherwise rushing can lead to deformation and damage to the fabric. Initially, the edges are processed on the sides, then the curtain is bent, well ironed and sewn.
• Next, a braid is attached to the top of the future curtain, bending the edges of the canvas by 2-3 cm. The ribbon is applied from the seamy side of the product and sewn. The number of seams in this case depends on the width of the tape. The bottom of the roller blind should be double-hemmed.
• The completion of the work is considered to be the drapery.

How to shorten roller blinds in length

The choice of design for small rooms, attics is associated with the problem of decorating non-standard windows. The situation is saved by roller blinds or roll-up blinds. They fit tightly to the frame. They are convenient and easy to use. One problem. there are no short models on sale, although the width of the roller blind can be adjusted to the size.

Cutting open structures is simple: just reduce the length of the canvas from above, tear it off the roller, straighten it, cut it. We fix the edge with glue on the tube.

Some people prefer not to disassemble the roller, the fabric is cut from the bottom, leaving an allowance of 5 cm. It is necessary to make a drawstring for the weighting agent. Without it, the canvas will dangle.

It is more difficult to trim closed roller blinds or curtains. We carefully remove the fabric from the guides, reduce it to the required length.

The guides themselves also need to be subtracted. We take out the plugs from them, cut the plastic with a knife, aluminum. with a hacksaw for metal or a jigsaw.

We remove the burrs, align the cut, tuck the canvas into the guides, install the plugs in place.

Installation on a wooden window

The installation procedure is slightly different from installation on a plastic window.

Preparatory work and installation features

Before installing curtains on wooden windows, you need to do the following:

• Open all doors.
• Wash windows and remove dirt from the frame.
• Let the window dry.
• If there is paint damage, or the paint is peeling, loop the surfaces and sand through them.
• If necessary, paint the frame. This is especially true on the side of the window where the curtains will hang.
• Start marking brackets or cassettes.

Before installing curtains on aluminum windows, you must:

• Open all the hinged window sashes or slide the sliding doors together.
• Wash the glass and the aluminum surface of the frame with warm water and laundry soap.
• Dry the window.
• Start marking brackets or cassettes.

How to assemble and install roller blinds: step-by-step instructions with installation rules

Tell: Ekaterina Belaya

Roller blinds can be installed on any known type of windows used in residential construction. plastic, wood, aluminum.

Features of installing roller blinds on a wooden window with a window

The best option would be to attach the structure to the wall or ceiling, especially if the opening is deep. there is room to open the window. However, not everyone is satisfied with this method in the case of narrow window sills and the presence of curtains / tulle.

Placing a curtain over a window opening does not always look like the best option.

There remains one more option. to attach the curtains to the frame, taking into account the vents. This side can be equipped with two mini-canvases to suit the size of the pieces.

The best option would be to place a separate curtain on each window sash.

The step-by-step attachment process is next.

First. assembly of the shaft part. Before that. measuring and calculating the length and width of the structure. For accurate marking, attach the assembled product to the frame.

When measuring, take into account the location of the handle. It is important that it does not interfere with the movement of the curtain.

Scheme of installing curtains on self-tapping screws with drilling

It is important! The method of fastening with self-tapping screws is preferable, since when changing the window design, the holes will be easier to seal and update.

If the canvas is too long, then it is recommended to carefully cut the bottom, making an overlap for the weighting agent. It can be inserted through the connector on the side.

Windows with a vent can be fitted with mix series curtains, which have a non-standard unwinding. In them, the roller is attached at the bottom of the structure, and the roll rises from the bottom up.

For brown wooden frames, you can choose a plastic mechanism and a canvas of a similar range or two or three shades lighter. The window looks better if the colors are matched to the wallpaper palette or curtains. When choosing a scale, pay attention to the size of the room. So, a lilac shade will visually reduce the space, and a snow-white shade will increase.

For day and night structures, it is preferable to mount to the wall rather than to the frame. If necessary, the blade can also be cut to the desired height.

Against the background of light walls, curtains in a contrasting color look spectacular

If you plan to mount the device to the ceiling or wall, then you need to choose a model with a web overlap on the sides (up to 3-5 cm) and a curtain of the appropriate length, otherwise, after installation, gaps will be visible that visually spoil the picture.

Advantages and disadvantages of roller blinds

When preparing to choose a model, you should pay close attention to the advantages and disadvantages of this type of structure.

Roller blinds can be matched to different interior styles

The advantages of roller blinds are as follows:

• Versatility. Possibility of combining models with a variety of interior styles.
• Aesthetics and brevity. Strict forms in combination with high-quality canvas can transform a living space, attic or loggia into a modern look.
• Practicality. Curtain maintenance is minimal.
• Reliability. High-quality products have a large margin of safety.
• Functionality. Using roller blinds, you can provide any level of light access to the room.
• Electric-powered models allow you to control them from a distance (for example, while lying in bed).
• Replacement of curtains. Blinds go well with tulle, so there is no need for full-fledged curtains.
• Saving space. Such a curtain does not require the construction of curtains that go beyond the window.
• Low cost. You can choose a budget model with a great design.
• For convenience, the products are always accompanied by assembly and operating instructions.

The roller blind can be plain or patterned

The disadvantages of roller blinds are minimal. These include:

• minimalism (not always combined with classic-style interiors);
• require special installation for plastic windows and structures with vents (rather not a minus, but a feature).

Mini roller blinds for blind windows

Fully closed sashes sometimes require a uniform roll-up design. When making such openings, you can use curtains with mini-rollers.

The kit includes a roller bar, brackets, line blade and clamps. To fix the curtain on a blind window, you need to do the following:

• Determine the size of the future roll in width and length.
• Connect the roller and the canvas as indicated in the instructions.
• Attach the open drum or cassette to the brackets using self-tapping screws (suitable for wooden structures), tape or mounting glue.
• The excess length of the web is shortened.
• A fishing line is threaded along the edges of the roll from the roller to the bottom, which is fixed with clamps or simply tied tightly at the ends.

About roller blinds: what is it, device, types, how to install

The history of the use of drum type window curtains goes back a long way. The mystery of the popularity of such designs lies in the practicality and ease of management. Over time, roller blinds have learned to make aesthetically pleasing, and not just utilitarian. This gave rise to a wide variety of models. And if Roman blinds create coziness, then roller blinds have more functionality, although a number of models are not inferior in terms of design and harmony.

Roll-up curtains are convenient to use, look stylish and modern

Installation of the product and ways to improve the design

The configuration of the windows assumes the use of one or another installation option. The classic installation. mounting flush with the window sill on the wall or ceiling. is not always suitable for roller blinds due to the specifics of the design. But this method is used. Let’s see how best to strengthen the curtains so that they fully fulfill their purpose, depending on the material and design of the opening.

Features of installation of roller blinds for plastic windows

For windows made of plastic, any kind of blinds are suitable, including exotic ones made of bamboo, etc. They look interesting and unusual, bringing their “zest” into the strict design of the opening.

Self-assembly of roller blinds on PVC windows requires special care. It is important to take into account that the design involves opening / closing the sashes in different positions. Therefore, the canvas and other parts of the curtains should not touch the guides and window mechanisms.

When placing a curtain on a swing sash, consider the thickness of the case, which may interfere with the free opening of the window.

Making only frames (more precisely, sashes) made of PVC is a relatively inexpensive and fast way. It is better to fix the top with double-sided tape or glue, since traces of self-tapping screws if you need to change the decor are more difficult to remove.

The fastening in the form of double-sided tape may gradually weaken, therefore it is recommended to hang a light roll on the sash. This method is not recommended for models designed for the entire width of the opening. Installation should be done with closed windows so that the structure is attached evenly.

A curtain with a drum hidden in a mini-cassette looks very neat on a PVC product. Ideal for matching white cabinet windows.

Such a curtain practically merges with the window frame.

So that the hand can freely open the sash and fix it with the regulator, the chain is located on the opposite side.

With an excessive length, the canvas can be shortened and a U-shaped weighting agent can be made at the bottom. Due to this balance, the roll will not dangle much from the draft.

The stages of work are as follows.

• The parameters of the base are measured for the future design.
• The adhesive tape is attached to the roller holder on one side, and to the sash frame with the other. Instead of tape, you can also use special glue or “liquid nails”.

The procedure for installing curtains on tape

The second way is to mount a roller blind with a spring mechanism. The product is installed in an already assembled state.

• Marking is made for fasteners. Brackets and a drum are installed on them.
• Lids are put on the side parts.
• Check the drive travel and blade tension.

Roller blinds: types and features

The control principle of these comfortable curtains is reminiscent of Roman designs and horizontal blinds. Now this option of curtains in combination with the usual curtains is common for apartments and private houses, as well as in business centers. They create a barrier to excessively bright natural light, which not only can interfere with rest, but also affects the preservation of the color of the wallpaper and the interior environment.

You can pick up roll products that are suitable for the price depending on the purpose

There are several types of roller blinds. Their diversity lies not only in the control method, but also in the system features. There are two main types:

Open control mechanism. The roller is in visible accessibility, not protected by a cassette or other type of cover.

Open type roller blind

Roller blind with protective box

The principle of operation of the structure may also vary. There are 3 control options:

• using chains;
• by means of an electric drive;
• with a spring clip.

All methods are convenient in their own way. When choosing curtains, be guided by many criteria that are individual for each place and lifestyle.

Indoors, 4 types of canvas are used:

• completely transparent;
• dimout (light transmission 20-30%);
• blackout (100% opaque);
• “day Night”.

Semi-transparent fabrics are used, as well as non-textile materials (bamboo, jute, etc.), which have their own degree of light transmission, depending on the model.

On a note! Many curtain options (plastic, metal or wooden box / roller) in any color, including white, allow you to choose the one that suits your environment.

The device and principle of operation of roller blinds

The bobbin type of construction assumes the presence of several components. The roller blinds device includes:

• roller with control unit;
• canvas;
• weighting plumb line;
• guides;
• adjusting mechanism.

Roller blind device with body and side guides

Roller blinds work on the principle of winding and unwinding the fabric onto a drum. It is located at the top of the structure. To tension the canvas from below, there is a weighting agent. U-shaped or a bar, with which the roll cannot sag or twist.

The classic mechanism is controlled by a chain. Magnetic stupors can sometimes be found in modern models.

To limit the stroke, a stopper is installed on the chain

The mechanism controlled by a chain drive has its own peculiarity. The balls on the cord are part of the hinge structure when the roller spins to one side or the other. They also act as a kind of clamps. The finished sample has a chain slope of at least 2/3 of the blade length.

Convenient roller blinds that rise from the bottom up using a spring mechanism. They have good tension. Reliable spring cushions the blade, which can be fixed in the desired position.

It is interesting that curtains with a spring mechanism can be installed in various positions.

The winding of the roll can be direct or reverse. The second option is typical for cassette curtains.

Guides help distribute the canvas evenly as you scroll. They also cover the sides from the gaps.
