In this tutorial we learn how to rig a fly line. Start by preparing the floating line or sinking line to accept the fly. Carefully unwind your leader, then fasten it over the perfection loop and thread it through the fly line perfection loop. This should make a nice tight knot so you have a nice tight fly. When finished, you can remove the leader then coil it back up and make three loops and save for use later on. It's also smart to carry a pack of weighters in your vest so you can throw them away later instead of littering the river.
