A few ideas for using glass blocks in your crafts include making dynamic picture frames, Christmas ornaments, candle holders, and lights. The glass blocks can be easily opened up in order to place a picture, candle or light inside.
Some ideas that can be found on Pinterest.com incorporate bows, ribbons, sequins, and paint. One of the more popular crafts to make out of the glass blocks is a Christmas ornament such as a present or snowman. For something a little more simple, a candle holder can be made out of the block by removing the top face and placing a small wax candle or candle light inside.
