Not only would this set (and matching die set) be great for a Xmas card & gift for your mail delivery person, but just for happy mail. Santa could be hauling that mail bag around town or just saying hello, just because or hi, I plan to use that mail box for a card to Santa.
I've stamped and cut multiple images to keep on hand and colored some. The dies are great. I like to have pre-cut images so I can just pull what I want out without also stamping, cutting and then being able to color. I sometimes color the images with colors I know I use frequently.
