My favorite way to eliminate the often paralyzing fear of "ruining" "good" paper is to just paint on any and all junk mail that comes into my house. Higher end catalogs are great for this, they don't use slick, thin paper (and even that gets used in collage or as a desk cover for other projects) and they're already bound for you. Just add marks! Carry it with you. Scan the pages you like. Cut it up later for making other art. It's "just" junk mail, so there is literally no pressure. I have HUNDREDS of these type of things and I run across them all the time, forgotten, in some old backpack or purse or drawer and it's a treasure to look through them again, and add new marks, paints and words.

What started off as a mess up ended up as a cool doodle. I plan on putting it up on my bedroom wall, maybe Walton will feel less hollow since he'll have some good company. I think everyone has a little bit of Walton in them at one point or another..
