Hook:
#2 Gamakatsu B10S or Mustad Stinger

Thread:
flat waxed

Materials:
Tail - sili-legs
Body - estaz chenille in colour of choice
Foam - closed cell foam in colour of choice - cut to about the width of a ice cream stick and 3.5 inches (9cms) long with a sharp blade.
Eyes - gold 3D

Instructions:

1.   Lay a base of thread along the hook shank and finish with thread behind hook eye.

2.   Take 4 or 5 strands of sili-legs double around thread and bind down back to the hook bend. Trim so they they extend by one hook shank length past the bend.

3.   Take the foam and make a cut down the middle extending for about an inch (2cms) from the end.

4.   Place the foam under the shank with the slit either side of and up against the hook bend. Secure with half a dozen wraps of thread. Put a small piece of foam over the hook point to stop it damaging the body foam.

5.   Attach the end of the chenille at the hook bend and move thread to about one hook eye width behind the eye.

6.   Apply a little head cement to the bindings and along the length of the shank. While the cement is still wet, hold the foam out of the way and wrap the chenille forward to just behind the hook eye, tie off and trim excess.

7.   Pull the foam forward and tie down just behind the hook eye with two turns of thread.

8.   Double the excess foam backwards and secure with thread. Whip finish and apply some head cement to secure.

9.   Trim the foam level with hook point and cut the foam down the centre.

10.  If desired, attach the eyes and cover with a small amount of Softex or Softdip to secure.

Notes:-

1.   Wide gape hooks are preferred so that there is still sufficient space between the foam and the point to allow a positive hookup.

2. Vary the colour of the legs and body to suit local conditions.

3. Tail can be constructed from rabbit fur or marabou however, as these materials become waterlogged, the fly doesn't roll over as well when it hits the water..
