I saw someone on YouTube make some super cute glass pebbles where they colored the back with nail polish. The only problem is that then she didn't show what to do with them. Most people make them into magnets, bit that idea didn't appeal to me. Some more searching showed that a lot of people glued ring backs or flat-back bails to them, but I am a super paranoid person when it comes to trusting just glue on non-porous items.
I had considered using a bezel, but the ones I have are from the craft store for floral decor, so they are all kinds of different sizes and shapes. I even tried to make my own bezel out of polymer clay, but I ended up covering more of the front than I wanted to before I felt like they would really be safe in there.
I then though of how I love making beaded netting, but how it usually takes too long to easily make something. I combined that with the idea of a bezel and these are what I came up with.
