This ATC uses a couple of the techniques Tim Holtz demonstrated in his 2010 Day 11 Tag (12 Tags of Christmas). I love the idea of creating stamps to match the die cuts I have!
For this project make a stamp out of the snowflake on the edge die cut. Use fun foam in the die cut machine to cut out stamp and glue to piece of plastic packaging for the back. I only had thin fun foam, so I cut out two strips and glued them together.
