Tim Holtz papers to make the base of the card and the letters for don't panic.
Lots of distress inks (mostly vintage photo, forest moss and crushed olive) - I used the faux enamel technique (see here) for the inner panels and the key and keyhole.
Tim holtz dies - cogs and gears, steampunk on the edge, and hardware findings
A mixture of clock themed stamps from Tim Holtz, PaperArtsy and Stampattack (free stamp with Craft Stamper magazine).
I borrowed the idea for the style of card from someone's blog, but I can't for the life of me find the link or remember who it was, so apologies to whoever it was and thanks so much for the inspiration.
Thanks for reading
