This is a piece of flip flop. I think some folks hammer them out with tubing or use Dremmel Tools - I do believe this wedge was cut out with scissors. Recycled bluegill popper bodies!!!!
STEP 1 - Tie in body at slim end - this is a quad or penta cut body WEDGE - try to think cone.
STEP 3 - After wrapping hackle - pull foam body forward and tie down = make some semi-loose wraps and pull thread tight.STEP 4 - Tie in legs - place some on one side and wrap. Repeat on other side - pull tight but not too tight.
Step 5 - Half hitches - tie it off.
