Hi there!
I have the 1999-2000 102 pin set framed and get alot of compliments on it. The frame is about 30 x36. I had it done in two layers. The back layer is black brushed velvet foam core board about one quater inch thick. The pins are pressed into it, in order of release, with the two "corrected" pins in the last row. In the very center I put a four pin set of Mickey,Donald, Goofy and Pluto holding hands that says 2000 on them.
Then there is a layer of dark red velvet foam core board that forms 3" border mat around the pins. On the inside edge is a gloss black fillet about one quater inch wide. It forms just enough airspace to raise the glass, so its a shallow shadow box. The glass sits on top of the border and the frame is a gloss black. The pins haven't moved or come loose so far and the colors of the pins stand out against the background. I'm pretty happy with the way it all turned out, and if there is any money left from our next trip I plan on doing a similar one with my "holy grails".
