It's a hand-crocheted bridal garter. I'm going to make two; one for Ian to throw at the reception and the other to keep. Actually, the pattern I have is for a pillow edging, but I modified it a little bit. When I make the second one, I think I'll use a slightly larger hook--but for the most part, I think this one came out well. I really love the rings in the center. They remind me of wedding rings. :D
If anyone wants a copy of the pattern (with my modifications,) just let me know.
