I made a glass necklace charm- Sweden!

I've been testing out some ideas for glass pendants for necklaces. Similar to the "oh so popular" scrabble tile pendants, these involve sticking your paper to the back of a polished glass tile and then waterproofing the whole thing.

I got this kit from KristenKrafts on Etsy.com and used a bit of an old map. This one was a present for my brothers girlfriend. Yes, she's Swedish! My lucky brother :)

What do you think? Have you tried one?

Would also love to learn how to make the full resin ones. Any tips?
