The base card is one of Regal's singlefold black cards (trimmed slightly). The silver "ttolbox" background is Cuttlebugged shimmer card. The black and silver cogs have been cut using Spellbinders Tim Holtz cog dies. I've just added some silver split pins and a few dabs of black ink to finish.
I really like the cogs set.....they look all very industrial here, but they're great as flowers in bright colours and you can even use them for Spirelli.
