I tie a lot of detached body patterns using my own dyed micro chenille. The Caddis fly in a few of it's life stages lends itself to using a wide gap hook such as the Kamasan B160. In tandem with the detached body I use dyed biots for wing cases.

The Dying Process:
I have always dyed my own materials simply because the color palettes of many materials at retail are very limited. Depending on where you live insect colors are very subtle and vary throughout the season so as a frustrated fly tyer I have always dyed my own materials.
The dying process is very very simple and I urge you to try it! Find an old coffee maker, some white vinegar, and some Veniards or Ritt dyes. The recipe is as follows:
~8 Cups hot water that has run through your coffee maker 150 degrees max heat ( use a thermometer)
~2 Tablespoons white vinegar, mix into hot water
~Add 1 tablespoon of liquid Ritt dye to hot water, match your color ways stir for 30 seconds
~Add your materials once water has reached 150 degrees F
~Test dye times and take notes as you experiment!
~Once you pull your materials out of the dye bath immediately soak in cold water for a minute or so, then use a hair dryer to thoroughly dry.
This is a very simple fly to tie, and it is a fly that I always carry in my fly box. Hope you enjoy tying the detached bodied caddis, happy fishing.
