Over at Green Paper Mary Green hosts a collage challenge every month. She provides 3 images from her extensive collection and you can make anything you like using at least a part of all 3 images. It is a fun, creative challenge and I try to participate whenever I can. For the April collage challenge I decided to make an ATC. I printed the images to fit on 1/4 of a page instead of a full 8 1/2 x 11" page. I think this size worked, what do you think? I used Adirondack Color Wash in lettuce, a brown watercolor crayon and a rubber stamp that has been in my collection for 20 years! Of course I cannot resist a little metallic marker!
