Yep, that's the pattern that I learned. It wasn't many years after that class that I saw an article in Flyfishing and Tying Journal that showed me how to tie some more detailed chironomids and hadn't thought about the TDC since.Can't help with the Hobby Lobby but the TDC midge pattern was one of the first I tied and fished, here's a good link: http://flytyingnewandold.blogspot.com/2011/11/tdc-nymph.html
In thinking back, we were pretty unsophisticated tying midges like this but they worked very well. Impressionistic.
Perhaps many of us should remember Dr. Thompson's fly and technique for fishing it. I know I get stuck in a rut sometimes......... good history, Tom!I heard about the TDC back in the early 1970's, but it wasn't until an encounter with Dr. Thompson on a lake in the mid-70's that I had success with it. He told me to retrieve it very slowly, just enough to keep slight tension on the line. The slow retrieve was the key. The PKCK was a great pattern too, and was tied in olive, brown, and different colors.
Since then, lots of new chironomid patterns have been developed, using flashy and translucent materials not available in the 60's and 70's. At some point in the 1980's, strike indicators became acceptable, popular, and effective. I use indicators all the time now, but held out and used Mr. Thompson's "naked" technique for many years.
