Tie these guys up in small sizes ie 20-26, and use different colored threads for different effects as the body is translucent. Be sure to tie them in red, yellow, black, olive, and brown.
Fish them with a greased leader(floatant on the leader) or dry dropper, whenever you see trout making those midge rings, and be sure to be ready, cause you will be surprised sometimes at the size of trout you can catch while midging.
