They're great. Sturdy, clean up easily (when i don't let the paint or gesso dry on them). Great for mixed media projects, cards, scrapbooking. Especially perfect for me since I don't have much ability to draw. I own a box full of them and have not been disappointed.
This is a fun template to use for many scrapbooking layouts. It can be used for a cool background, or use to crop photos for an interesting display.
