Wing Slip from a waterhen primary quill, tied 'penthouse' fashion (1 slim slip)
How to tie it
Run the black silk from behind the eye to above the barb, then forward two-thirds.
Twist a very sparse pinch of mole's fur onto the silk and wind a slim dark body over the rear two-thirds of the shank.
Spiral the olive silk forward in 3-4 evenly spaced turns to rib the dark body, then tie off.
Tie a slim slip of dark waterhen primary low and tent-shaped over the body ('penthouse' fashion), extending past the bend for the long antennae, and secure.
Build a small black head, whip finish and varnish.
