Hi Brian, I’m impressed – the best ideas are often the simplest ones. I’ll have some Cuben Fiber scraps when I start on my next MYOG project: a few waterproof 20 Ltr. stuff sacks (as part of my pack - the TFD pack 2.0).
I’ve bought the Cuben but, since I’ve never worked with it, I’m still studying the way to put the different parts together (having read nearly every single post on this subject in this forum, it looks like bonding is the way to go). Thanks for sharing the idea, because this pouch seems to be a perfect starting project.
