If you have not played with the water color crayons from SU! I think you really should ask your demo about them, if you don't have a demo I'd be happy to hook you up.
They are a great way to color images or make pretty backgrounds. This was so simple, scribble the crayons on the water color paper (just like when you were a kid) then use an aqua painter or a paintbrush to blend. It's a super fun way to make a background.
NOTE: some say stamp first some say stamp last. if you stamp last make sure your paper is 100% dry or it will be a mess. I stamp first!
