Glass Acorns - not sure if this is really DIY, but worth a shot. One of a kind glass acorns were created using an "off mandrel" technique-meaning they are essentially a solid drop of glass with only one hole. The artist used real acorn caps to top off each one giving them a light sealing with Renaissance Wax. Extremely durable-No two are alike.
