Apartment Therapy has an ADORABLE project using Scrabble game pieces to label your books.
… this diy project could be a simple solution to labeling your shelves with a bit of spunk. You can find Scrabble games by the dozens at thrift stores (and could probably find more by placing an add on Craigslist for old sets).
Each tile was glued to the tray, so pieces didn’t go flying if it was knocked. What other games would lend themselves to something similar?
