If your kiddo is serious about his art, then he might need an apron like this one. It includes pockets sized just right for holding crayons within easy reach. Care from Obsessively Stitching shows how to make one. Get the tutorial.

I got this Apron at Target and my kids love it…They don’t have individual crayon pockets like the one above but pretty much the same idea http://www.samandbellie.com/product_p/snb-apron2.htm
