I’ve started making some fabric face-masks, but I have no elastic for the straps, and don’t really want to place orders for supplies that might not arrive for up to a month. I have plenty of 550 paracord, though.
The first few were just tied in place, but I knew I could come up with something better, that was faster, and more easily adjustable. I had a vague sense of the shape of a device used by mountain climbers, but no idea what it is called. It took a few iterations, but this one seems to work pretty well.
UPDATE: After trying these out with several different brands of paracord, I have started sizing these up to 1.25" to make it easier to thread the cord through the holes. Someone else noted they were sizing them to 1.38". It could be a good idea to test with the paracord you will use.

maybe you can use it.
