Today we have a free instruction for a sewn mouth mask. This can be very helpful for people with allergies and health problems. But it is also indispensable in times of corona crisis. It is not 100% protection against bacteria and viruses, but it certainly helps to reduce the risk of droplet infection. With our instructions you can also sew this washable mouth mask. On the inside above the nose, a metal strip or wire can be inserted into the sewn-on fabric pocket for better fixation.
