One of our last art projects was glue on black paper with oil pastels and that turned out so great we decided to try another glue project. For these I let the boys freehand draw with pencils a pumpkin picture. I let them look at a picture I drew for reference. Then we traced the drawing with glue. We let the glue dry overnight and then the next day colored and blended using chalk pastels. They had so much fun blending all the colors and the finished projects turned out great!!!
