I'm always looking for my next new bag. In my recent searches I discovered this fascinating set of bags
by Josh Jakus. I like my geometry a bit more random than he does, so I decided to adapt the idea to a more non-regular surface. The design and construction are pretty simple and, assuming you can get your hands on a sewing machine, you should be able to pull this off for less than $20.
Please leave comments, I'd really appreciate it!
