Step 1: Set up
Spray your flat surface with window cleaner. Place the doubled bags on the wet surface and spray that as well. The window cleaner will give you some freedom in placing the tape. Don’t worry it will dry without effecting the performance of the tape.
Step 2: Duct tape strips
Continue overlapping strips until the entire bag is covered. Next, apply a layer of strips vertically. When that’s done flip it over and do the same to the other side.
Apply cleaner as needed to keep it from sticking before you want it to.
Step 3: Trim
Apply tape to the bottom and sides to cover the seams exposed from trimming. Also apply a single horizontal strip of tape over the zip-lock area to aid in pressing the zip-lock closed.
Wipe off any remaining window cleaner from the exterior of the pouch. Place a couple paper towels in it and let it dry over night. In the mean time make the adjusting strap.
