From Tuesday Stitches:
Like the giant snail shell for which this bag is named, you’ll want to carry the Achatina Messenger Bag with you wherever you go. This easy-to-sew messenger bag is great for throwing over your shoulder for whatever your day may hold. The front flap makes the perfect canvas for graphic appliques or for showing off unique fabrics. It closes with a velcro tab and has an interior pocket with an optional zipper closure (for intermediate sewists). The pattern includes 5 full-size applique designs for use on the front flap and instructions for raw-edge appliqué. Dozens more appliqué patterns specifically designed for the front flap are available in Appliqué Expansion Packs.
