The new box of crayons

I have exceptionally warm memories of the few times I was given a new box of crayons, and a few sheets of my Uncle Geoff's cast-off architectural plans. Flip the plan over and you have a giant sheet of slightly scuffed and slightly yellowed but decent quality paper. The possibilities that opened up were endless, although the resultant drawings never quite matched up to the masterpieces of my mind's eye!
