We used 9"x12" canvas panels and I had the students tape off the bottom section in a wavy line. Then we painted the top part with watery acrylic paint and spread plastic wrap over it while wet. After a minute or two the students lifted off the plastic and tape to reveal the cool stripey effect. While the canvases dried they sketched out simple tree branches and cut out lace circles. Once the background was dry they used sharpie markers to draw the tree trunks, then mod podge to adhere the lace to the trees and seal the canvas. The mod podge dries pretty fast so we were able to add small red birds to the paintings using toothpicks and the back end of a brush (two dots for the head and body and the toothpick to draw the tail and beak). Simple but fun.
