Step 1
Mount a hook in the vise,
tie in the thread and cover the thorax area with thread. |
Step 2
![Bi-Color PTN - Step 2](flies/steps/bicolorptn/step_02.jpg)
Measure a
bunch of pheasant tail barbs. The front part, with the tips,
should be about 1,3 - 1,5 x the total body length of the
fly. |
Step 3
![Bi-Color PTN - Step 3](flies/steps/bicolorptn/step_03.jpg)
Tie in the
bunch so the tip part point out forward past the hook eye. |
Step 4
![Bi-Color PTN - Step 4](flies/steps/bicolorptn/step_04.jpg)
Fold the
rear part of the bunch up over the thorax area and secure it
there. We're using this surplus part to build up a little
larger thorax. This way we get the bulk above the hook shank
and keep a maximum hook gape. This makes this technique very
suitable for hooks also in the smaller size ranges. |
Step 5
![Bi-Color PTN - Step 5](flies/steps/bicolorptn/step_05.jpg)
Cut the
waste of the surplus end as close to the thread as possible. |
Step 6
![Bi-Color PTN - Step 6](flies/steps/bicolorptn/step_06.jpg)
Cover the
rest of the hook shank with thread and tie at the same time
in a piece of copper wire or ordinary round tinsel. |
Step 7
![Bi-Color PTN - Step 7](flies/steps/bicolorptn/step_07.jpg)
Tie in a
bunch of lighter colored material, here yellow pheasant tail
barbs. This fly should be seen more as an idea than a
pattern, since it's open for a lot of variants while still
keep the advantages of the actual bi-color technique. Note:
If weight is to be added, now is the time to do it. |
Step 8
![Bi-Color PTN - Step 8](flies/steps/bicolorptn/step_08.jpg)
Here the
yellow pheasant barbs have been wrapped up towards the eye
and been secured at the head of the fly. |
Step 9
![Bi-Color PTN - Step 9](flies/steps/bicolorptn/step_09.jpg)
We are
done with the thread work and a whip-finish is made in a
regular manner. |
Step 10
![Bi-Color PTN - Step 10](flies/steps/bicolorptn/step_10.jpg)
Now it's
time to get imitative. |
Step 11
![Bi-Color PTN - Step 11](flies/steps/bicolorptn/step_11.jpg)
The darker
barbs are folded back over the hook shank and tied down with
a wrap of tinsel/wire at the end of the body. A darker back,
a wingcase and a tail are created in one swift move. |
Step 12
![Bi-Color PTN - Step 12](flies/steps/bicolorptn/step_12.jpg)
Continue
to rib the wire forward and tie down the back barbs in
segments. |
Step 13
![Bi-Color PTN - Step 13](flies/steps/bicolorptn/step_13.jpg)
At the
start of the thorax, finish off the wire with a couple of
half-hitches and cut the waste. |
Done...
![DONE!](flies/steps/bicolorptn/step_14_1.jpg)
And here
it's done. Quick, simple and imitative with few materials.
Strong factors defining a "perfect" fly. |
Variants
![Another...](flies/steps/bicolorptn/step_14_2.jpg)
Smaller
hook with olive body. |
![And a third...](flies/steps/bicolorptn/step_14_3.jpg)
Another
variant, with yellow SLF dubbing for abdomen and peacock
herl for a thorax, but still based on the very same idea. |
