This unique colouring book will introduce you to many attractive designs made up of rectangles, squares, and other basic geometric shapes. You'll find stars composed of triangles, a large box filled with cubes, an interesting design of many-sided figures, and other eye-catching patterns - all boldly outlined on translucent paper.The pictures are printed on special paper that allows light to shine through. First cut the pages from the book as neatly as you can. Then colour the pictures, using crayons, felt-tip pens, or paints. You'll get particularly interesting effects if you colour both sides, using different colours on the backs than on the fronts. When the pictures are taped to a window, the sunlight shines through them the same way it shines through coloured glass.
