Flash Blending Fly



In the Flash Blending write-up, I wrote about blending flash materials and synthetic fibers to create your own custom blends not commercially available. This pattern is an example of how to use these blends to create baitfish imitations. The only limit is your imagination. The technique is very useful for constructing mid to deep-bodied baitfish. Depending on the colors you use it could imitate herring, bunker, pollack, mackerel, etc. Here is how it’s done.


Short shank deep keel hook such as Varivas 990S. The deep keel helps to insure that the fly tracks straight. The fly in the illustration was tied on an Eagle Claw 254ss, which I bent to shorten the shank and deepen the gap. I also bent the point on a slight upward angle to help eliminate deep hooking.

Step 1

Place the hook in vise upside down as shown. Take a bunch of flash blended material (usually white or a light color) and tie it on to the bottom of the hook shank at a point approx opposite the point of the hook. The material is tied down at its mid-point with half the material pointing forward and the other half pointing to the rear. The size or diameter of the bunch of material will be determined by the final result or profile you are trying to achieve. Experience will teach you the proper amount to use.

Step 2

Fold back the material that is pointing forward and tie it down at the same tie-in point on the bottom of the shank. If you were careful to tie in the material at the center point, when you fold it back the two halves will extend rearward ending at the same point. It’s a good idea to put a drop of cement on the wraps at this time.

Step 3

Rotate your vise or put the hook in the vise right side up. Repeat steps 1 and 2 with an equal amount of material on the top of the hook shank, again cementing the wraps. This tie should extend the same distance as the material on the bottom.

Step 4


Advance the thread halfway between the first tie-in point and the hook eye. This will be the position of the next tie-in point. Rotate the vise or turn the hook upside down in the vise and repeat steps 1 and 2, using the white blend on the bottom of the hook shank. Invert the hook once again repeat step 3, this time using a dark color on top. If you prefer you can stack two or more colors of blends on top at this tie-in point. If doing so you may need to keep the bunches sparse to avoid excessive material build-up. Be sure to keep all the thread wraps at the same tie-in point.

Step 5



Advance the thread to a point just behind the hook eye. Repeat step 4, again using white under the shank and the colored blend or blends of your choice on top. Keep all the thread wraps as close to the eye as possible and avoid building up a huge head. Cement on prismatic eyes with goop or a hot glue gun. Apply cement to the head. If you have layered several colors of materials on the fly it will probably have a striped appearance. What you will want to do now is to comb out all the material with a hair comb. This will blend the colored layers so that the colors will gradually blend into each other and have a more natural look. The final step is to trim the fly to shape using a pair of long bladed scissors. Do most of the trimming on the bottom materials of the fly to achieve a deep rounded belly, leaving the materials on top full length.
