I was at a local hobby shop and found some artificial sinew, which I completely forgot existed.
Now, some of my leatherworking friends use it in their hobbies. Does it have any practical uses for bows other than stringing together a leather handle or perhaps bowstring?
Nope, makes crappy strings for that matter.
Some folks make bow strings from artificial sinew. It stretches a lot but I think they pre-stretch the strings once made.
I only use it for leather stitching.
Same here, leather grip stitching.
