This is a triple layer card and my new favorite technique. It is very popular right now. Here is a video of the technique. http://www.youtube.com/watch?v=bmculp_tz74
I used a set of stamps I got from Tuesday Morning.
This one is done with a digital stamp from http://www.whimsiedoodles.com/ . The background is an old stampin up stamp. This is colored with bic markers
The truck and saying are also from http://www.whimsiedoodles.com/ It is colored with colored pencils. The key is from another set of stamps. I don't remember which one. The white chain is a punch.
Here is the final one from this class. It was one with a resist technique. Here is the video that gave the idea. The flower is a felt sticker I had. Something I got on clearance years ago.
