Cut a sheet into one by two feet pieces. Place a two-foot long piece of string in the middle of a piece. Fold the piece over the string. Loop the string over your ears. Flop the outer half of the piece over your head. Tie(or knot) the string around the lower half of the piece and your throat. Fold the top half of the piece back down. Put on eyeglasses to close off bridge of nose openings. To remove, cut string if exposed to hazard and discard, or if not, slip string over ears for reuse.
