You are welcome ladies!
Jacquie, I use mostly 16 to 18 but I have have all the "tools" for all the sizes and have some of the other sizes. I like these snaps because of the tools. I still mess up sometimes but not like with the Dritz. I could never get those right but with this the snaps are "forced" to be lined up and I get it right almost always. And they hold good too.
