Thick HDPE 1/16” (high-density polyethylene) sheet

Looking to add structure to a bike bag? Or sew a frame for your backpack? These HDPE sheets are PERFECT. They're easy to use and so versatile. I was intimidated by this at first but sewing machines just glide right through it. With a solid pair of scissors or boxing cutting knife, you can cut it to fit your pattern, drill holes to lighten the weight if needed, and sewing on your aluminum stays like the second photo(also available in my shop)!
