1. Insert a hook into the vise and build good thread base.
   
   
2. Tail - Tie in 5 or 6 strands of Black Krystal Flash slightly into the bend of the hook extending 3/8" beyond the bend of the hook.
   
   
3. Shell Back - Trim the 3/8" (9.525 mm) wide strip of black foam to a shallow point and tie in at the tail tie in point extending to the back of the fly over the tail.
   
   
4. Ribbing - Make a loop of tying thread long enough to rib the body plus secure the shell back.
   
   
5. Body - Tie in the orange sparkle yarn immediately in front of the back material and wrap forward about 2/3 hook's shank length. Secure with tying thread and trim the excess close to the hook's shank.
   
   
6. Shell Back Again - Pull the shell back forward over the top of the body and secure with tying thread at the front of the body. Trim the excess foam strip and leave approximately 1/8" (3.175 mm) clear of the tie in.
   
   
7. Ribbing - Wrap 5 turns of ribbing around the entire fly to mold the shell back around the body yarn material to leave a thin strip of orange between the sides of the foam back at the underside of the fly.

   The instruction above is identical for the Delta and Original Foam Stone. Next is specific instruction for the Original Foam Stone.

8. Wing - Immediately at the front of the abdomen/shellback tie in a cleaned and stacked 3/4 pencil sized clump of light elk hair. The tips of the wing should be slightly proud of the hook's bend.
   
   
9. Upper Thorax Half -Trim a 3/8" (9.525 mm) foam strip to a point and tie in tight against the wing tie in.
   
   
10. Lower Thorax Half - Reverse the fly/hook in the vise (bottom side up). Trim a 3/8" (9.525 mm) foam strip to a point and tie in so the tying thread wraps from the wing and upper thorax are covered. Pull the lower foam strip forward and secure with tying thread 1/8" (3.175 mm) behind the hook's eye. Trim the excess foam close to the hook's shank and cover with tying thread. Turn the fly right side up in the vise.
    
    
11. Upper Thorax Half - Pull the upper foam strip forward and secure with tying thread even with the tie off of the lower foam strip. Trim the excess foam, cover the butts with tying thread, whip finish and cement if you like.
