This is something I've seen lots of people doing lately. I went to the store thinking I would get an open backed frame and just use poster board or cardboard to "pin" into. But I found this cool ready-made bulletin board. I took it apart and covered the board with the polka dot pattern and then started pinning in my jewelry. I couldn't find any super cute pins so I just used the old standby dritz pearlized kind. I really like this one because it has those 3 little compartments at the bottom. I can put my watch and other big stuff in there as well as spare pins and post-backed earrings. I think it turned out really well. I can also hang belts from the hooks at the bottom!
My only concern now is the size...What to do when my jewelry collection no longer fits on it?!?
