Using up paint

As I go through all my art supplies to sell off at Cottage Crafts in Campbell, I have some things that aren't good enough to go into the ZZ booth. I have a lot of bottles of paint (and I can't remember why I have so many) that aren't full enough to resell. So instead of tagging and packing, I decided to try and use up what I had and make backgrounds.  Since I have the paint and the paper (trying to use up all my glossy paper) I spent the day making a huge pile of backgrounds. I have been thinking about stocking my card rack at Cottage Crafts and donating all the profits to the war relief efforts. It's getting a little challenging as I have packed up most of stamps so I have to use what I can find.
