I played around with some paints and a credit card to make these background papers. You just squeeze out a little paint along one side of the paper (one color) and then kind of squeegee it across the paper with a card of some kind. Follow immediately with another color. You could use a playing card, but those fake credit cards you get in the mail with all those credit offers work great! You just keep adding colors right over the top of each other until you are satisfied with your result. I used a number of colors on the first one, but only two colors on the other. They're both great looks I think. I love the grungy chaos. You can add to that grunge look by going back over your swipes of paint and "cutting" in with the edge of the card. It scratches down into the other layers of color.
