How super cool is this card! I love it, stamp the tree, mask the moon and sponge the background. Then cut it to look like a window pane!! Using the Special Season stamp set from the 2013 Holiday Catalog. Created by Laura Barto,
The window / moon is created using the circle punch and a post it note as a mask. Just like I did in this video from a few years ago: http://stampwithtami.com/blog/2009/10/video-tutorial-brayered-night-sky-holiday-card/
