Here is our crayon roll. I don't usually do things from patterns or recipes, but just lay it out, use a few pins and sew.
I let the girls each pick out a fabric and they just happened to complement each other. I would've sewed it up no matter what they picked, though. One side is for block crayons and the other side for stick. This could also easily be made to fit pencils. We use beeswax Stockmar crayons made with natural pigments. Sigi has an excellent dvd on using block crayons that I highly recommend. The girls share these crayons. I'm not a huge fan in having separate things of the same for the girls. I expect them to share things, and they do. I mean, they each have their own drawing pads of course, but too many things of their own I think encourages selfishness. They most likely will neither become hermits so the sooner they learn to share and cooperate with others the better for them.
