      • Pin the liner and new fabric panel together, so that the 'right sides' of the fabric are facing outwards.

      • Set your machine to the longest stitch length (usually 5 mm), and the loosest thread tension.

      • Not every machine will allow you to adjust the thread tension. If yours allows you to adjust it, set it to zero.

      • Sew the layers together with a 1/4" seam allowance.

      • Turn the backpack right side out.

      • Look along the new seam for any of the stitches that hold the lining and base fabric together, and remove them.

      • Pin the binding around the bottom seam, so that it sandwiches the seam allowance.

      • Allow one end of the binding to remain loose.

      • When you reach the loose end of the binding, connect the end that you already sewed with the loose end.
