I tried to find what I did when organizing school supplies made from cereal, detergent and dishwashing soap boxes. I turned them into a tray, covered in decorative contact paper, with empty paper towel/toilet paper rolls for pencil/marker holders. Also plastic containers like Hershey's cocoa became small item holders. I would cut holes in the box 'tray' and set the holders into them, they fit snuggly.
Lots more ideas now thanks to crafty blogs and Pinterest.
