Cut a fly screen straight and to fit

Opinions are divided about how a mosquito net can be cut to size. While some simple scissors are sufficient, others describe the grid and net edges as frayed. However, since they are only visible in grids and nets without a frame, the problem is negligible. Cutters and wallpaper knives are also possible.

Leave the overhang

In general, a fly screen should only be roughly cut to size before installation. An overhang of at least two centimeters in all directions is only adjusted after installation.

While the cut for a given frame can be measured correctly relatively easily, this endeavor is more difficult with free-falling fly screens and mosquito nets.

Make final straight cuts

Fly screens are similar in texture to textile material. They should always be cut flat under slight tension. Either a weighting or a second person can help.

A line drawn with chalk will help keep scissors straight. With a cutter or wallpaper knife, the cut on a cutting bar made of metal or wood is straight. If the insect screen is stretched into a frame, it must be cut "roughly" as the end cut is made after it has been clamped to the frame.

Cut the corners tightly and neatly

If corners are trimmed from the outer edge, the cuts must be made at a 45-degree angle towards the future corner. The cuts look like a miter.

For some ready-to-buy frames, the manufacturers supply triangular corner protection inserts. This can also be easily implemented when building a fly screen yourself. This eliminates the risk of the corner developing a slot or hole at the joint of the cut.

The iron reserve

If possible, overhangs of about one centimeter are left on the top or bottom edge and on the left or right edge. They can be optically hidden by folding or rolling in. This "iron reserve" helps later, should the fly screen bulge due to a loss of tension, to retighten it.

Tips & Tricks Use only sharp cutting tools. With blunt blades, the risk increases that the edges of the mosquito nets will fray and look plucked. If you want to cover visible edges, two centimeter wide adhesive tape, for example made of textile fabric, will help.
