One of my 6x6 scrapbook paper pads had a sheet of romantic-looking rose illustrations in little squares. I cut one of these out and used a corner rounder to soften the edges.
I used only doming on this project - no mold. The resin is poured directly on the surface and allowed to self-level right out to the edges. Surfact tension keeps it from pouring over the edges.
I decided to mount this one on angle and did so with E6000 glue and a gold pail.
