This simple design features easy construction and the convenience of zippered pockets. Sew it up from heavier fabric for a "pack" look or make it from a lighter fabric for a bag in the folk craft tradition. This pattern has two versions: center pull straps (for lighter weight fabrics) or side pull straps. Add optional outer and inner zipper pockets and a D-ring key holder to organize all your extras.
