I used a piece of cleaning cloth to make the mask. The nosepiece was made from the top half of a juice bottle. I made holes in the cloth, then I stuck cellophane over the top of the holes for eye holes. Then I stapled elastic on the cloth for the straps. The top of the bottle is the original filter. The top has holes in it. For Red Nose Day, you can even use your red nose as a filter for it!
