Three-dimensional mask (3D mask) -You can put non-woven or kitchen paper in the mask!
Sew a patch
In the photo, the lining of the mask is made of double gauze.
Gauze fabric is a delicate fabric.
Therefore, sew a patch cloth to reinforce the part where the nose-bridge strip is put.
This cloth mask can be washed many times.
Size of patch
After sewing the front fabric and the lining together, sew the part where the nose-bridge strip is inserted.
The size of the patch cloth is 1 cm (≒0.39)in× (length of the nose-bridge strip+ 4~5 mm(≒0.15in～0.19in)).
Sew a patch cloth longer than the nose-bridge strip.
