It's a lot easier to thread the eye of the darning needle with the end of the mono than to try to thread the mono alongside the nail. Once you have the nail knot formed, but before you tighten it, adjust the loop in the fly line so you are using only a couple of inches of line for the loop. Then, tighten down the nail knot.
