I've been planning on making some book bags for quite a while now as Miss 11 is an avid reader and rarely goes anywhere without a book of some kind. It always upsets her when one of her precious books gets knocked about in her school bag and a leaking drink bottle is a disaster! I attempted one version with a flap and magnetic clasp closure which proved way too difficult to sew together since I was using plastic on the outside.
I ended up using the "Snap Happy" bag pattern by Stitchin' Sisters and just adjusted the measurements to fit a good sized book. I also sewed across the bottom corners so that it would have a flat bottom and used a layer of plastic over the external fabric to protect it a bit more...... Miss 11 is delighted! I just need to get busy and make a couple more now... Such a great gift for any reader and I could use one myself too!
I just love how this pattern uses a piece of old metal tape measure to make the snap closure....very clever!
