Thank you all. Patrick, I think for me 3 ply sinew strings are the easiest and strong enough for 1000-2000 shots, yet narrow enough for a fast arrow. I use backstrap. not pounded, just teased apart and brushed to a fine silk sized thread. I start out with a thicker bunch(1/3) size of string, then add a few threads whenever it starts to narrow a little. Do a pretty tight twist a little longer than 3x the finished string. Then fold it in 3. It will start to reverse twist it self. I twist it tight then hang it with a weight braced so it does not untwist.
