Ok, I'm confused by the instruction.

Step 2: Tie in two olive ostrich herls and make 2/5 of the body. DO NOT cut them for now.
Step3: Tie in two orange ostrich herls and wrap a "hot-spot" exactly in the middle of the fly. Proportion has to be 1/5 of the body.
Step 4: Wrap remained olive ostrich herls to form the front 2/5 and tie off.

How come in Step 4, I'm not palmering through the orange herls and screwing up the look?

Nice fly, btw.
