A bowstring is usually affixed to the bottom of the bow, in the lower nock or notch, with a timber hitch. The bottom one may be made small so that it fits tightly. These are the wearing points and should be protected.
Good whipping is tedious work, but it doubles the life of a string.
Linen is the best fibre of which to make a string. It is very strong and does not stretch. Stretch in a fibre is an objection, a bowstring must always maintain one length. Making a Bowstring of Linen or Flax Twine Cut off a piece of flax twine. This twine is made of four lays or plies.
