I hate to waste any of my art supplies and more often than not, when I have been playing with paints, I find that I have a bit extra leftover. I just can't bear to watch it get washed down the drain, so I add water to what is left to really dilute the pigment, then I sop it all up with wet paper towels. I think that leaving them to dry on a slightly scrunched plastic bag might help contribute to the texture. Here are a few that turned out kind of interesting. These have all been pressed flat, so what you are seeing is the way the colours dried, blended and the lines that were created. (click on the photos for a closer look)
What do I do with them? Well, this is a postcard I recently made for our quilt guild's exchange. The only "fabric" is that small bit of selvage edge, the rest is painted paper towel that has been stamped and heavily stitched.
Easy, simple, and best of all..........nothing is wasted
