Sinew Cord: Two Plies of Sinew Reverse-Wrapped
Sinew is extremely strong, holds its own natural glue and shrinks as it dries. Circumpolar peoples used it as their only cordage. Twist wetted sinew threads into two plies and wrap them round each other the opposite way, so the twists lock into a cord.
The picture: string made from whale sinew in Tierra del Fuego, collected in the late 19th century.
