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. Butterflies included are Monarch, Red Admiral, Angle Wing, Swallowtail, Aphrodite, Fritillary, Copper and Morpho. 8 pages.
