Keep your mind engaged while you create beautiful art with Sticker by Number Vintage Butterflies. Includes 28 images to sticker, featuring butterflies and natural settings. Images range in difficulty. Perforated pages make the book easy to use. Made for adults but kids can enjoy as well! As in color or paint-by-number, each design is divided into dozens of spaces. Each space has a number that corresponds to a sticker. Find the sticker, peel it, and place it in the right space. Watch as a full-colored image emerges from the original unfinished illustration.
