- Fold one end of webbing 1/2 inch under and fold the other end of the webbing down, so they meet each other. This gives you three layers to sew into, plus will add strength to the straps. These backpacks need to be tough since they might get thrown around on a playground. If you're unsure about the straps, look at a purchased bag that already has this type of strap in order to lace it correctly.
- Place adjuster on the back panel at placement marked and stitch close to edges (figure M), 3/4 inch above bottom edge and diagonally from corner to corner. Sewing an "X" design helps to make these nice and secure.
8. To make the handle, mark the center of the webbing and 2-1/2 inches on each side of center mark, then fold webbing in half lengthwise, between the marks and stitch together.
9. Pin webbing to back with handle toward top. Just fold the webbing open, pin just below the stitches and that is where you pin it and where you will be stitching it to the back panel.
10. Stitch a one-inch square and stitch diagonally from corner to corner and be sure to stitch only through strap and back (figure N). Insert ends of straps into strap adjusters (figure O). You may want to look at a garment that you have at home to see how these get properly laced through the adjusters. At end straps, fold a 1/4-inch hem and stitch. You can do this before or after you feed the webbing through the adjusters.
