Comparadun deer hair


  1. Start thread behind eye of hook and wind halfway down hook shank, then halfway back towards eye. This is the proper tie-in point for deer hair. Placing thread on the hook in this manner prevents deer hair from spinning.
  2. Clean and stack a bundle of deer hair.
  3. Proper wing proportions should be length of hook.
  4. Extend tips past hook eye and tie in with two loose thread wraps. Pull straight down on thread so deer hair flares. Do not let go of butt ends and wrap 8 – 10 times evenly toward tail to firmly secure hair. Trim or tear butt ends.
  5. Move thread to back of deer hair.
  6. Sweep deer hair backwards to allow hair to stand straight up. Thread should be immediately behind deer hair. Sweep 1/3 of hair back and place 1 thread wrap securely in place by pulling straight down. Sweep next 1/3 back and place 1 thread wrap securely in place and pull straight down. Sweep last 1/3 back and place 2 – 3 wraps at base of deer hair. This technique allows minimal thread wraps to stand deer hair up without a thread dam.
  7. Wrap thread to hook barb.
  8. Tie in tail and split.
  9. Attach THIN amount of dubbing and wind forward, leaving one thread wrap behind deer hair (if you don’t, it will force hair forward). Bring dubbing directly in front of deer hair and begin figure eight wraps around hair. The first wrap behind hair, you’ll feel it snug tightly and force hair straight up. Remember, THIN dubbing will work better to create tapered body.
  10. Whip finish behind hook eye.

The Comparadun is a style of fly and can be used to imitate many mayflies, including Pale Morning Duns, Blue Wing Olives, and Green Drakes.

      Thanks for your comment. Superfine is a type of dubbing sold by a few vendors, including Wapsi and my local Oregon company Hareline Dubbin. Most fly shops will carry this product in a variety of colors…and March Brown is a popular color…email sent.
