Natural Sinew, Eastern Whitetail 10"-12"   One-ounce groupings because of their lengths and weight (No less than three full lengths or more).   Rolled out with all sheathing and scrap pieces removed. All usable sinew.  Rolled out for you to gently separate apart to whatever strip width you are comfortable with. The sinew threads in tendon doesn’t run straight. It crisscrosses back and forth. That’s why it’s hard separate into long threads. The concept of collecting bundles of threads came from pretty far back. You can pull outwards on it until you have a wide crisscrossed band.
   Would save hours of work not processing each tendon, you don't pay for scrap. Great for bow backing, replicating.  

I combine shipping charges.
