-- use tacky glue instead of sewing & use ribbon to close. Also instead of blank paper use coloring book pages. Overall super easy craft! A bit labor intensive(no quick way to cut slits for crayons & books) but very easy!
@ Lauren- something for boys-Portable LEGO Tray - Brilliant! You could even hang these on the wall of the toy room. Also, great for a portable play surface for the kids when away from home, just make to fit inside a book-bag or back-pack :-)
