Carp, I haven't gotten the ones from Molly so I will let you know how I like them when I get them. If they are good I will ask her if I can get some for you. I do believe she made them to tie on, not elastic.
My good friend that is our mayor sent to me via messenger a video of a woman making them out of a cut up t-shirt...no elastic, no sewing needed. The woman is speaking a foreign language, but you can figure out how to do it by watching. I can try to send it to you via email.
