G's favorite page in Pat the Bunny has long been the peek-a-boo page (the one that uses a cloth flap to cover Paul's face), but it only recently occurred to me that it would be easy and fun make a book filled with peek-a-boo flaps.I used pieces of felt (because they don't fray) and glued them on with a glue gun (so they would stay put). There is a place to purchase blank board books here.
