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.

Here is a sneak peaks of my submission to the Home Sweet Home Challenge. I loved this challenge because it forced me to do something I never would have, which gave me happy surprises as I worked through it.
A friend asked me to make this. Should I make it into a sticker or print?
Uni Posca marker, watercolor, and neocolor watercolor crayons.
I added this guy to redbubble, he is available as a sticker, notebook, phone case, etc.
I told my boys, "That's you, you and you." They paused for a moment, pointed at the hot dog, and asked, "Well... Who's that?" ... "That's your baby sister." -- Ink and watercolor on 5x5 Arches cold press.
