Coloring your own field guide, from the peachy white of a Knobbed Whelk to the pinkish purple of a Tulip Mussel, is the most enjoyable way to learn about shells. Each drawing is accompanied by a brief description that educates as it entertains. Place the new color stickers next to the drawings for a visual reference while you work. Coloring the drawings helps reinforce the image, shape, and colors of each shell, improving your memory and perception while offering a pleasant and easy way to learn. Fun for adults as well as children, beginning and experienced naturalists alike.
