Do you like the monochromatic look? I enjoyed making the backgrounds to go with the cards. I need to do this more often. It makes you feel "artistic" to stamp a pattern.
I was asked in a comment about the sizes of the layers. Here are the sizes: The card base is cut at 5-1/2 x 8-1/2 and folded in half, making the finished card size 4-1/4 x 5-1/2 inches. The bottom white layer is cut at 4-1/8 x 5-3/8 inches and the top stamped background layer is cut at 4 x 5-1/4 inches. A helpful hint is to stamp the background layer on a larger piece of cardstock and then trim down to size.
