I found Ripstop by the Roll after stumbling onto the Make Your Own Gear subreddit, I think while doing some research into lightweight backpacking. I didn’t have any sewing experience, but the ZPP Kit was on sale so I bought it on a whim.
I picked up some bias tape from the thrift arts and crafts store. The sewing machine is my housemate’s. The kit is very straightforward and there are a number of videos on YouTube which guide you through making it.
