Here's another simple 15-inch bag.
#8 cotton duck (~18oz), lined with 1000d Cordura nylon.
I hand washed all fifty yards of the cotton. Although it's treated with something, I wanted to make sure it doesn't shrink after I turn it into bags. I also washed out some of the extra dye. It's crazy how stiff this fabric gets when wet.
Made a cutting table especially for this project. Gonna be makin' a lot of these bags.
