I had never sewn bags before, but I've wanted to for a while.
As a mom and errand-runner, diaper-hauler, mail picker-upper, and library book-carrier, I expect a lot of the bag I'm using. Many times it is required to haul all of those items at the same time! So they wear out...
Well, now I can make a new bag when I need it, in my choice of colors and with my own inside pocket configuration.
I can't tell you exactly how I made the bags because I didn't use a pattern. I started with some ideas in my head, and learned as I went. The basic shape is a rectangle a little wider than it is high.
I had some help with the zippered pocket tutorial from here.
In fact, these turned out too small to be my perfect right-hand bag, so they were Christmas gifts.
