I made 10 of these for my son's preschool teacher. I put one hole for scissors, one for a glue stick, one for a fat pencil and 24 for a pack of crayons. My wonderful husband did most of the work, 4 hours of drilling all 270 (!!!) holes one Saturday afternoon in a friend's garage (we used their drill press - thanks again Morgan!). They were a ton of work, but so worth it! I hope all the kids like them.
