A slightly more advanced version of the mask is done in much the same way as the previous one. A strip of gauze or a wide bandage measuring 80 x 40 centimeters should be folded along the long side, then measure about 30-35 centimeters on both sides and cut along the middle. These will be the ties. In the middle part put a quadruple gauze or bandage folded – you should get a square with a side of 20 centimeters. In Joom you can have the best choices.

Such a mask can be worn for several hours, after which it is not necessary to throw it away – you can wash, dry and iron with iron in the “cotton” mode before reuse. And if you sew a square on only three sides, it will be possible to change the “filling” separately and thereby increase the number of “cycles” of use.
