craftgrrl | Glass Nugget Magnets

I just got done making some glass nugget magnets. But they aren't really magnets, cuz I didn't buy any magnets yet! I was so proud of myself! : ) I used a YM Magazine, and some of my Mom's clear glass nuggets she uses for stained glass. I used clear fingernail polish as the glue on some and rubber cement on some others. I just used that to glue the picture to the nugget, and they dried up really well. I still need to put something on the very bottom of the nugget, but I don't know what I should use, and if I should cover the whole nugget, or just the bottom. So can someone help me with that?

Thanks! Katy
