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 large, 12-3/4-inch by 15-3/4-inch, format of the junior large painting by numbers was selected to offer a project that was a bit more challenging than ourjunior small series and the introduction of color mixing takes it to the next level. Conforms to ASTM D4236. Recommended for children ages 8 and up.
