I don't know how I didn't know these printables were available since my daughter LOVES anything and everything Harry Potter! The free printables for all the books in the series are available from American Girl Ideas and are already perfectly sized for your dolls. I printed them out and using my craft knife I cut some pieces of foam to make up the insides of the books. I can't wait to show my daughter when she comes home from school! So awesome, thanks American Girl Ideas!
