This ATC is inspired by some of the techniques Tim Holtz used in his 2008 Day 6 Tag (12 Tags of Christmas).
Tim used a Clear Paintables sheet. I didn't have one of those, but found a Acetate Die Cut in my stash that could use some more color. I think this technique could also be done with images printed on transparency sheet. Here I choose a section of the sheet that would fit on my ATC.
