Method #2 Striped Chenille Body from The Fly-Tiers Benchside Reference
This technique produces a body from two strands of material spiraled simultaneously along the shank to make stripes. Striped chenille bodies can be used to imitate specific naturals or simply to produce the broken color pattern that is often characteristic of living creatures.
We’re using highly contrasting materials to illustrate the technique, which produces a boldly striped body, but more subtle color combinations—browns and olives, for instance—can produce quite lifelike effects.
Note as well that different sizes, textures, or types of chenilles can be combined with this method to give the body a segmented or ribbed appearance, or to introduce a bit of flash.
A similar type of body, with distinctly separated bands of color, can be produced by Method #111: The Banded Weave, p. 195. (Order the Fly-Tiers Benchside Reference)
Step 1. Prepare the two pieces of chenille by stripping the ends as shown in Method #1: Simple Chenille Body, Step 1, p. 99. Twist the thread cores together as shown.
Step 2. Bind down the combined cores at the rearmost thread wrap.
Hold the two strands close to the hook shank to keep them as close together as possible. Wrap the strands simultaneously, keeping an equal and even tension on each strand.
Step 3. When the tie-off point is reached, bind down both strands at once, using the procedure described above in Method #1: Simple Chenille Body, Step 5.
