The pages in this book are printed on both sides of translucent paper. The images create a stained glass effect when colored and placed against a window or other bright light source. Pages can be colored with crayon, felt-tip pen, acrylics, watercolor, tempera or oil paints. Or, colored tissue can be applied to the transparent surface. Color both sides for the most dramatic results. 8 pages of round designs filled with circles, squares, triangles and other figures. Paperback measures 4-3/16 x 5-5/8".
