Disclaimer: I tried to do the same technique with different designs from Tim Holtz's 2007 Day 6 Tag, but my efforts look very different. Make cure you check out his tag, as I love the look of it!
I have problems with the masks. They work great the first time, and then, I don't know, either I don't know how to clean or my work space is to dusty or something. I can not get the masks to stick as well after that first use. Anyway, following directions, placed a mask on my card and sprayed over it with a home made mist (I used one I'd already done up with light brown re-inker and gold Perfect Pearls. Let air dry, then remove mask.
