Add Lining and Strap and Finish Bag
1. With right side inside, fold black-and-white floral 6x16" rectangle in half to measure 6x8" (Diagram 6). Sew together along long edges. Turn and press under raw edges 1/2" to make bag lining.
2. Fray 1" of twisted cord end to separate strands. Sew cord strands to inside of outer bag at one side seam with three or four rows of short machine stitches (Diagram 7). Trim ends. Repeat with remaining end of cord at opposite side seam.
3. With wrong sides together, insert bag lining into outer bag, matching seams. Hand-stitch top folded edge of lining to top of outer bag to complete bag.
