I am making both fitted and folded cotton masks with an opening to add your own filter. I'm using t-shirt material for the ties and making them so they wrap around your head, but they go through a sleeve on either side so you can replace it with whatever works for you.
I'm not charging for medical or essential people, but I am asking for a $3 donation from everyone else to help me buy materials. My venmo is @valamyot and my paypal contact info is firstname.lastname@example.org
If you need me to ship I have flat rate envelopes ($7.75), small flat rate boxes ($8.30), medium flat rate boxes ($15.05) depending on quantity. I have fit 15 masks in a small flat rate box and could probably cram a couple more in there.
DISCLAIMER: This is NOT a medical grade deal, guys. You can use it to cover a "real" mask or you can add a filter but I am NOT promising it will protect you from zombies, covid19, and sharks. The studies I've shown says a single layer of cotton protects you 70%. This is 2 layers and your filter. Better than nothing, right? Please use your judgement, be healthy, and be happy.
