Marc Petitjean demonstrates how to use his Magic Tool to tie a basic Caddis pattern using just 3 CDC feathers is this fly tying video tutorial.
Marc Petitjean Magic Tool – Is it Really Magic?
Well not really, but it certainly makes tying in CDC feathers in a wrapped hackle manner using a split-thread technique a whole lot easier.
The Magic Tool is not cheap but if you tie a lot of CDC it’s probably worth it. You can pick one up on amazon here.
Enjoy!
