I picked up a deep frame, mounted them and gave them to dh for father's day. It was a huge hit and it's hanging in the family hallwall gallery now. He's getting another one this year.
Michael's has the frames, shadowbox frames I think they call them, they're about 2" deep and come with Velcro to put on the object you're framing to hang on the backing board. I just bought one on sale for $5 and it took less than 5 minutes to frame.
