We go through many, many crayons at our house. I buy several boxes of the 24 count crayons during the back to school sales when I can get them for a quarter a box, and we use them all before the next year. I have always figured the 24 different colors were enough for the kids to draw what they wanted, but this last year E1 convinced me to splurge on the 120 count box. She was right; they have really used the subtle shades.
