The number one jewelry seller store on Etsy sells only Scrabble Tile Pendants :) I googled it and was surprised! It's fairly easy to do. I made a couple myself using beach background a piece of sea glass we found here on Maui but I have to locate where I stored the pics. I still have a lot of scrabble tiles left too :)
Learn how to make this yourself :) She has a link to the tutorial.
