I'm working on a little paracord rock sling. I weaved the pouch separate so I could experiment with different arm lengths, but it left a lot of messy untidy ends.
The tutorials I watched on youtube make the whole sling out of one piece of cord, but they also use a large needle to guide strands through at the end. They look very neat but I still prefer the idea of a separate pouch, think I'll scratch my head on it for a while
Really tricky to use though, people make it look very easy but it's tricky.
