I made and sold the notepads, last year. Found Christmas ones for kids sold the most. Grannies were buying them, and the smaller ones made with the kind you get in the Dollar stores. I envy you as in the UK we don't have such good quality ones.
Notepads cost 30 cents each. Sold for $1.50, I printed some Christmas Pictures and coloured in with pencils, Cheap and Cheerful, but I did sell 20 of them.
