I tied all of these on size six wet fly hooks but they can be tied on many sizes. All the thread is 6-0.
The first one:
Thread: Olive
Tail: Olive feather tip
Body: green dubbing
Hackle: Large soft hackle feather, Olive
The second one:
Thread: Olive
Tail: Olive hackle feather strands
Body: Olive dubbing
Hackle: Olive hackle feather
The third one:
Thread: Black
Tail: Black feather tip
Body: yellow dubbing
Hackle: Orange hackle feather
All of these will float some when first cast but are fished much better below the surface.
