History of the Overhand Weave

The history of the overhand knot weaving technique is a bit sketchy. Some give credit for the idea to Hank Roberts. Hank has always given his wife credit for coming up with the process, but there is more to the story.

On the same day that Hank claims his wife came up with the idea, he also claimed to have received in the mail a package with flies tied with the same technique. Along with the patterns was a letter asking Hank if he wanted to buy the patent rights to the process. Hank bought the rights some time around 1953. As far as can be ascertained, Dan Vercellino and Al Ross sent the package and sold the patent rights to Hank Roberts. Dan Vercellino lived in Idaho and was tying flies with the overhand knot weave. He and friend Al Ross obtained a patent for the process around 1947, and formed a company called Century Products.

Based on this information, it can be assumed that the weaving technique Hank's wife came up with is the same one that Dan Vercellino came up with. Both are given credit for this technique.

Torill Kolbu of Norway performs the same weaving methods by using crochet hooks. Some tiers may find the use of hooks helpful, but if you can learn the hand movements, hooks are not needed.

Other types of weaves are:

Overhand Knot Weave

Knot

  1. Tie in the material for the body. This can be yarn, embroidery yarn, Larva Lace or any other material suitable for weaving a body. Larva Lace is easier to work with when learning this technique: it is smooth and doesn't fray like yarn-type materials. Choose a dark-colored material for the back and a light-colored material for the belly. Tie the material in on each side of the hook shank. Bind the material down toward the bend of the hook. For these instructions tie the dark material on the far side of the hook shank and the light material on the side of the hook shank closest to you.
  2. Turn the vise toward you and lower it a little. You want to be able to look down on the top of the hook shank so you can watch the weave as it progresses.
  3. Begin the weave by taking the light-colored material with your left hand and passing it under the shank forming a loop in the material. This is held in place with the middle finger of the left hand, leaving the thumb and index finger of the left hand free.
  4. Take the dark-colored material with the right hand and pass it over the hook shank and down through the loop formed by the light-colored material. This will form a loop in the dark-colored material.
  5. Reach through the loop of dark-colored material with the thumb and index finger of the right hand and grab the light-colored material; at the same time grab the dark-colored material with the left-hand thumb and index finger. Simultaneously pull the materials away from the hook shank in opposite directions to form a knot around the hook shank. Make sure the knot is nice and snug.
  6. Continue this process until you reach the desired body length. The dark- and light-colored materials will change sides of the hook with each new knot. Be sure to take the light-colored material under the shank and the dard-colored material over the shank to get the desired look.
  7. When you get the desired body length, pull both colors forward and bind them down. Clip off the excess material. You have a woven body.
