1. Turn in 1⁄4" along upper diagonal edges of each bag body and bag lining section (Diagram 9). With wrong sides together, insert bag lining into bag body, matching folded edges of bag to corresponding lining section (Diagram 10). Pin in place.
2. Insert strap raw ends 1⁄2" between lining and bag body layers, centering ends at bag sides (Diagram 11).
3. Topstitch upper diagonal bag body edges 1⁄8" from folded edges, catching strap ends in stitching. Overlap stitching at lower V on each side to secure top of outer pocket (Diagram 12). Repeat on opposite side.
4. For outer pockets, measure and mark 3" from lower curve along diagonal edge (Diagram 13). Stitch over previous stitching through lining to make one outer pocket. Repeat on opposite side to make a second outer pocket and complete bag.
