Leather bag best

This leather bag is 7-1/2 inches wide and 7-1/2 inches tall, the gusset is 2-1/4 inches thick. The leather strap is 38 inches from end to end. The bag is constructed using waxed thread, which employs the saddle-stitch to piece the leather together. On the flap of the bag is a piece of leather cord that is in an cross pattern whose ends may be attached to the Dee-ring, to hold the flap of the bag closed. This bag originated from a saddle-bag pattern. Taking one end of the pattern creates the bag.
