Glowing skulls by CraftyGoat
All you clayers need to get ready for Halloween - are you aware that Fimo and Sculpey III have glow in the dark clay? And Sculpey Premo does too - and Premo also have fluorescent colours you can mix in. Making little ghosts or simple beads for necklaces that glow and you will delight the children. And I am sure you can come up with loads of other ideas - so add them here!
Hope you don't mind Penny, I'd seen the perfect picture for this post so I added it for you.
Glow-in-the-dark clay is awesome! I've seen it used for monster eyes, and I've used it myself to make a "magic" inscription on a stone effect pendant for a friend of mine.
