Backpack Base Replacement

Einleitung

The Ozark Trail Ot Whittier backpack is one of the most durable backpacks for its low price point. However, the sustained pressure of heavy backpack contents can cause a large tear in the base. The incision is usually along the line of the inner laptop compartment. Repairing a torn base is straightforward for those with sewing experience, particularly handbag and line garment experience. This guide outlines how to remove the base panel, cut a new base panel, sew the new panel in, and bind the inner seams. It is recommended that you take caution as an iron will be used in this project.

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.
