Years ago at one of my beginner tying classes, the instructor had us tie the Brassie, one of my favorite flies for fishing the South Platte River in Colorado which is the origin of this fly. The Deckers area of the South Platte can be very demanding and technical. Those fish have probably seen all kinds of flies but the Brassie in the right size will hook them every time.
The Brassie is a fly that can imitate both a midge and caddis larva. Here is how I was taught to tie the Brassie and some additional variations that can be very effective.
