My first attempt at bottle cap magnets

My mom enjoys purchasing soda in glass bottles from a local bottling plant for our big family get togethers.  The bottles are small, which is perfect for all the kids in the family, and they come in lots of fun flavors like cherry and grape.  This summer, at one of our family get-togethers, I saved a handful of the bottle caps.  This week, during my Christmas vacation, I finally decided to try making some magnets with them.

I purchased a 1" circle punch to cut out the designs.  After using an Exacto knife and some tweezers (pliers would have been easier) to remove the rubber from the inside of the caps, I used Mod Podge to glue the pictures in.  After researching a bit online, I wanted to try using Diamond Glaze to fill in the caps.  I didn't find any at Joann's though, and rather than running around town to look for it at other stores, I decided to try using Glossy Accents.  I followed the directions and did not shake the bottle.  There were still a few tiny bubbles, which I removed the best I could with a toothpick.  When the Glossy Accents dried though, there were tons of minuscule bubbles.  When this bottle of Glossy Accents is gone, I think I'll try something else.  I used an old tube of Goop to glue the magnets on.
Here are the finished magnets:
