DECALCOMANIA... You can't help but have fun when you press beautiful paint colors between papers or on a canvas surface and uncover the result to discover that the colors have mixed unexpectedly and left little surface ridges. You can let the results stand on their own or incorporate them as elements of a collage or larger painting. Another fantastic idea is to emphasize the textures and borders between colors by adding lines with a pen and ink or sharpie marker. The following example is an oil painting, but you can use tempera, acrylic, or ink just as easily.
