Glass House Cased Caddis Nymph

The Glass House Caddis Nymph is a pattern designed by western tyer Scott Sanchez. It is a great little cased caddis imitation, and can be tied in numerous colors. My favorite color combinations are: 

As shown- Black Peacock Case, Yellowish Olive Bead, Black Hackle
Variant 1- Peacock Case, Green Bead, Brown Hackle
Variant 3- Brown Case, Cream/Tan Bead, Brown Hackle
