I've been wanting to try and make one of these clasp purses for a while now but couldn't find the clasp. Anyway, last time I went to my craft store I saw them and had to get a few. This is the largest I got, about 4-5". They were kind of tough to make. I definitely have a lot of changes to make for the next one. Here is the LINK where I got the pattern and tutorial. It's a great blog with lots of free patterns and wonderful ideas.
