Great videos, I watched the whole series and I think if you can build your own flemish twist strings you can make one from sinew. I had no idea how sinew strings were made, but after watching the videos I know I can do this. Been making my own flemish twist strings for quite some time now but never touched a piece of sinew. The principles are very similar and makes me wonder who taught who? If this is how the Indians made their strings, then did they teach the Flemish or did the flemish teach the Indians? LOL
I also subscribed to your channel while I was there. Looking forward to seeing more how to videos cause I make some myself. I love making how to videos and watching others, nothing like seeing it done first hand to get the idea. So much easier than trying to explain it to someone.
