I have one coming from my quilt fabric store too. Hopefully it will work well because I only have enough bias to make 84 masks and my mom just put in a request to send a bunch that way. If I make 5 per person..uff da that’s a lot of sewing. I hate to change up my pattern if I can make them that fast to something slower. Checking with my friend to see if she needs specific kind. I may send her a few to try and then we can work from there.The ties take forever, so I ordered one of those bias tape makers. I haven’t used it yet, though. I mostly made them with elastic.
ETA: I was late to the elastic game. Not sure I want to sacrifice my hair ties when I’m keeping it up all the time now and always manage to lose them.
