Make books by cutting cardboard or balsa wood to size. Paint the edges white or gold and cover with thin suede, cloth, or paper. Then carefully glue the picture to the front. You can also buy inexpensive books ready-made (about $2 a dozen) and glue pictures to the front. If you are filling a bookshelf, you can paint gold lines across the spines.
