From Crayon to Colorwork
You can grab pre-made artwork on the website starting at $69 for a six-inch design created from 195 crayons, or you can go for the gusto and order a custom size from any image you want (up to 37-inches by 55-inches). Granted, the latter requires nearly 15,000 crayons and will set you back $3,229.
