Part 1 has some basics about sewing in zippers (it’s easy! really!!) and making various small bags and pouches that can be great as travel accessories, school supplies, a way to organize your backpack or all those chargers and cords, etc.

Part 2 extends the same concepts a little further to make two different styles of duffel bag. These look complicated and fancy, but I promise you they are easier than they look and quite accessible.

The commands below are laid out in a more-or-less narrative style, so if you're just getting started with bash, you can work your way through from the beginning to the end. Things generally get less common and more difficult toward the end.
