I decided to rust it up a bit using the trusty cinnamon method - the rivets were just large flat back pearls that I stuck on first.
That's Crafty! also made Craftboard sheets of key designs to go with the new stamp designs - this one is embossed in a mixture of silver and copper. The wings come from one of the stamp sets, stamped and embossed onto silver card that's been coloured with alcohol inks.
This is just the first of my keys - I'll show you the others at a later date.
Thanks for looking!
