I found this circle shaped mini card on Fabulous Finds Cricut Cartridge. I added a fun dimensional gem to the middle of the clock, but because of it's dimension I had to place a mini glue dot on the backside. What worked with this is the slight stickness of the glue dot helped to keep the circle closed. You may want to de-tackify the glue dot a bit, by rubbing it with your finger. The natural oils on your finger will make it less sticky.
