this is my favorite kind of bag! it has a ton of room, but it isn't a bear to carry. the snaps let you change the shape of the bag for even more room. there are two pockets, one for your cell phone, mp3 player, or other little things, and a pleated side pocket to tuck your wallet or small bottle in. pattern includes step by step pictures, templates, and an 'extra touches' section for optional features. cottage industry use included. BASIC SKILLS NECESSARY great advanced beginner pattern. should be comfortable sewing straight and (slightly) curved seams SIZING / FINISHED MEASUREMENTS 11" x 12.5" (17") x 4.5"
