These are Crayon Melt ATCs that I just finished for the 60/60 Technique swap on Art Techniques. I grated some old crayons with a cheese grater, placed them in between two layers of watercolor paper, and ironed them. Be sure to lay down an extra layer or two of plain paper on the ironing board, and on top to protect your iron. Then I layered different colors of diluted acrylic paints: greens, turquoise, and tomato orange. Finished it off with a little copper metallic. I'd like to try this technique with some other color combinations. Each card measures 2.5 x 3.5 inches.
