Carol's Convertible Purse from The Creative Thimble. This is a great changeable bag from a backpack to a handbag with the pull of two straps. This is an intermediate to advanced pattern.
From the back of the pattern: Finished size is approx. 12" wide x 11" high • Magnetic closure • Exterior pockets: 2 front pockets and 1 back zippered pocket • Interior pockets: 1 zippered pocket and 1 patch pocket
My general advice for handbag construction: make the strap and tabs first, then the pockets, last the body of the bag. Get everything ready to put together, assembly goes faster.
