Soooo... I used this stuff. Singer "snap fastener kit" - This actually came in a like grab bag of random craft stuff that I bought at goodwill for like two dollars. I basically bought it in order to get these snaps. and some ribbon.. Anywho. I managed to get the "male" half of the snap on properly with very little stress. However, the "female" was disastrous. I messed up three prong pieces in the process. and I ripped up the fabric some waaahh but the snap that stayed covers the issues.
I made some more of these things:
They can also be purchase at my etsy shop.
