What are you most proud of? Totally, completely green and Earth friendly! I use just about every part of a book that is destined for the garbage bin! What advice would you give someone starting this project? Easy, easy, easy! Just start with a perfectly square piece of paper and fold. There's no sticky stuff on the flap, so you can choose how (or if) you want to seal it up. I use plain white glue, or little stickers...they add just a touch more cuteness!
