This apple messenger bag seems fitting for back-to-school time, but I would totally carry it year round! Angelina from JoJo & Eloise and Ruby Jean shares a tutorial at The Ribbon Retreat Blog showing how to make it. An apple shaped bag seems like it would be fun bag to carry, but you could easily alter the design to make it in any simple shape. How about a kitty bag? Or a strawberry bag? You can follow her tutorial to make one. Go to The Ribbon Retreat blog for the tute.
