This tutorial shows how I make and attach the S-curved, contoured shoulder straps for the Talaria ultralight backpack. The tutorial includes five YouTube videos showing each step of the process, a printable PDF file with all the sewing templates and detailed text instructions for attaching the straps to the backpack. There’s also a full list of materials and an angle template. Here’s the free tutorial link:

There are probably faster and more efficient ways to make shoulder straps, but these are comfortable, versatile and appear to fit most people pretty well. If there’s interest, I may make a similar tutorial covering the entire Talaria backpack.
