This large bag has a specific purpose: toting all of your crafting or sewing supplies with you wherever you go! Although it would also be perfect for an art student, I designed this with the sewing retreat in mind. My friend, Brenda, from Pink Castle Fabrics, holds weekend sewing retreats several times a year called Camp Stitchalot, and this bag was named for her. There are outer pockets for a 12" x 18" cutting mat, books or magazines, and quilt rulers. The front pocket features a pretty flap and optional decorative button. To get to all of your other crafting supplies, the bag opens up completely flat. There are 4 inner zippered pockets, made from clear vinyl, which can be customized to fit smaller sections of supplies, just by topstitching the vinyl. All-in-all, this is a fabulous bag with so many possibilities! SIZING / FINISHED MEASUREMENTS 20" x 14"
