Bracelet Confusion

[hiatusteph.livejournal.com]

I'm having some bracelet confusion.

I bought beads, leather string, a clasp and "fastener" (like the ones pictured below), and small ring.

Obviously, I don't know the technical names of any of the pieces, but that's not what I'm wondering.

I'm wondering how to attach the string to the clasp and "fastener".



Thanks!
