[set fair (OP)]

One of the more important things about a mask is that it is comfortable to wear. This one only takes a minute or two to make (depending on how sharp your scissors are) and is comfortable enough to wear  for as long as you like.

Cut 12 inches straight up the middle of the front or back of a T-shirt.
Cut around the shirt so that you have a strip of material 12 inces wide
Fold in half so that the the strip is now 6 inches wide
Fold a piece of kichen paper in half and inset into the middle of the strip
Put the mask on and tie with a simple left over right and under slip knot
