Re: Cased Caddis
That pattern sounds very similar to a pattern Gary La'fontaine used to tie in the 'Traveling flytiers' seminars with Jack Dennis and Mike Lawson.
The only difference was, he called it his "Garbage Can Caddis", he would take all the clippings from his flytying waste recepticle, (feathers, tinsel, thread, yarn, flashabou, everything, it doesn't matter) chop is up, put it into a loop & spin it, wrap it and trim it square, add the legs and head.
Darn thing looked amazingly real.
