Be sure to use fabric that is 100% cotton (tightly woven for the front, flannel or other soft 100% cotton for the back). If you have any doubts about the content of your fabric, please do not use it. (Treadle staff can assist you in determining fiber content.)
Please prewash all fabric on hot and dry on high heat. This step is to ensure pre-shrinkage. Area providers will sanitize the masks.
You will note the instructions involve the use of elastic. If that is not available, you can use fabric ties (self-made ties, twill tape), one in each of the four corners. Each tie should have a finished length of 18 inches.
We have also been working to find more 1/8, 1/4, and 3/8” elastic. If vendors ship as promised, we should have renewed supply on Thursday March March 26.
Thank you in advance for your generosity. Treadle customers are the best!
Michele Hoaglund and all the Treadlettes
