I've always used Dritz products for installing snaps. I tried those pliers and the metal snaps, but it is so hard to manipulate them. I tried doing it by myself at Christmas when I made a hipster bag, but I was 7 months pregnant and felt that I'd inadvertently push that baby out with each squeeze of the pliers. I had to enlist the help of my husband to get that snap installed. And if I wasn't using the pliers, then I was using the hammer tool to insert snaps. But you can't use that unless you are outside on the concrete, because it will surely dent your wood floors.
Enter the Babyville Boutique pliers and plastic snaps. I bought them with a 50% off coupon at JoAnns, but otherwise I think they cost like $20.00, which is pretty steep for a tool, but the first time I used it without the aid of any man or woman, I fell in love! I think it has to do with the fact that the snaps are plastic and the plastic bends easier than the metal dritz snaps. Plus the snaps come in all sorts of pretty colors.
Anyhoo, the plier set from Babyville comes with a bunch of things: different sized snap parts, screwdriver for installing said parts, awl for poking through your fabric, and pliers, of course. The snaps come separately.
Anyway, you mark out where you want the snaps to go, take the awl, poke it through the fabric and you've got your little hole for the snaps.
Then you put the snap parts into the holes. I just followed the directions on the back of the snap packet for the order of the snaps.
After placement, you squeeze them together with the pliers, like so:
Do it to both sides and you've got some nicely installed snaps.
I made bibs for my drooling monster and it was lickety-split getting them all installed.
I don't know if they will stand the test of time. I'm sure those metal dritz snaps were made to last decades, but installation of them also feels like it takes decades. So yay for pretty plastic snaps!
