Simply follow the numbers. Royal & Langnickel has created a brilliant project for all ages. The painting by numbers kits are a terrific way to learn composition, plus a great stepping stone for painting on your own. Each project includes a pre-printed artist board, practice sheet, acrylic paints, paint brush and instructions. The small, 8-3/4-inch by 11-3/4-inch, format of the painting by numbers was selected to offer a project that could easily be tackled and finished in a short amount of time. Whether a rainy day project or a gift for a child, the painting by numbers kits provide pure entertainment. Conforms to ASTM D4236. Recommended for children ages 8 and up.
