Originally posted by macbow: It is just two loops the one on the bow hand is just big enough to,fit properly. The loop on the fingers can be aided with some shrink tubing to make it stiffer where the fingers fit.The knots are adjusted to for perfect length with the drawing arm and elbow in line when at anchor.Using this will give you the feel of perfect back tension.When teaching the kids in the NASP program they don't get to shoot the bow till all lessons,are,learned and demonstrated with the string bow.
