I haven't made a shadow box card for a while so thought I would give it another go. I cut the circle in the base cs using my cuttlebug and nesties after scoring the fold lines. The fish is between two layers of acetate, as are the rocks and weed (both free hand drawn). I used DCWV dp on the back sheet, and the blue dp on the front is American Crafts. I finished it with the greeting (part of the digi-stamp kit) and a button, and some peel off stickers that I think look a bit like bubbles. It's not a great picture as it's so hard to photograph acetate, especially at night with rubbish lighting!
Thanks for looking
