To create the background, I've done loads of masking using Tim Holtz-ideaology masking template. I've also stamped around it and add liquid pearls to it.
The handle and the key are actually chipboard. I've inked it with distress ink and cover it with perfect pearls. This is the "Creating your Faux Metal Pieces" technique. Later, I've covered it with some distress stickles to further distress it.
I've also added various metal elements on it to make all the hardware look more realistic.
It's really a fast and fun ATC. Hope you all like it.
