Hey man, you can still ask more questions if you want but I'll post a few high points.
- Tarred Twisted Bank line is available in several different sizes on Amazon depending on how hefty of a sling you want, usually I trend toward the smaller-medium sizes so I can taper the release cord.
- It's more durable than regular nylon, has very little memory, untangles easily, water resistant, and braids well in my experience.
- This sling can mostly be made following the "Simple Braided Sling" or a "Balearic Sling Making " tutorial with a couple small changes.
A. Start with 8 cords with extra to fold over the ring or 4 cords that are 2.5 times the length of the sling you want.
B. Add an extra cord when braiding the finger loop so you can use a 5 strand braid which I think is more comfortable.
C. Use a four strand round braid for the cords
- splice in more cords as you get towards the pouch
D. Use a five strand flat braid for the pouch
- Taper the release cord starting at about half way down.
- Sling on.
