Well, my first effort was terrible, my second effort however, seems to be functional.

I didn't have a press, so I just stood on a piece of wood over my foam. I used 2 layers per side of blue camping mat from Walmart. The roughcut was with a razor and the final was using a dremel and polished with some old blue jeans. I used a rivet die and hammer, but still split 3/4 rings. I think the rivets were too close to the edge for the die to sit properly.

The carbon fiber texture was in the close-out bin, but I don't think it looks too bad. Enough excuses, time for pics:
