I made some crayon rolls a few months ago, two of my daughters are teachers and use them for their table groupings. I found the pattern from The Pleat and Poppy through a link on Pinterest to make crayon rolls for 16 crayons. They were easy to whip up, I think I made 20 when it was all said and done. I cut the pattern length in half for some of the rolls. Mine looked similar to the one shown below, you can click on the link to go to an Etsy store if you want to purchase one.
