They’re all flannel: 2 pieces for the front and back plus one extra layer in the middle. Suitable for just when all that is needed is just a little protection.
Not only will these save so much plastic and fiber waste, they were made entirely from stash! I was able to use up some very small flannel scraps as well as the last bit of thread on one spool and two bobbins. I admit that a few were fussy cut for the sake of hilarity.
I used up these 3 partial cards of snaps, too! I think I inherited these from my grandmother, but some may have come in a thrifted baggie of notions.
