There is a really easy way to make masks from an old long sleeved t shirt. Cut off just above the hem so you have a circle about an inch and a half. Trim off one of the seams and put this strip around your neck with the loose ends hanging down the front. Cut across the top of one of the sleeves then cut that sleeve across about six inches down so you have a six inch tube. Put the two hanging down ends through the tube and pull them, flipping the tube up over your mouth and nose. Tie the loose ends behind your head, above your ears. Adjust the mask, pulling it down over your chin, to make a good cover for mouth and nose. I made two they are easy and comfortable. I hope this makes sense. I saw it on Facebook.
