I just added a few more tile to my SCS gallery...they are still pending though.
My first batch of tiles I just bought a small batch of jewelry bails from Michael's with a 40% off coupon but then I got addicted! LOL So I ordered 100 of the larger bails from China (they are the bails on my newer tiles). I have used all of those too! YIKES (I have a problem)
So I recently found this etsy store. I am still waiting for my order to arrive but they should work perfectly.
Welcome to the Bottle Cap Shop by BottleCapShop on Etsy
For the larger bails I am using the E-6000 glue but for smaller one I was just using the Tombow metal glue. I hope that helps
