METHOD #1:  head & hand knots (only) as shown by Rav Qafah zs"l in Mishnah Torah shel Ramb"m .
Arm and hand according to one Dor Dai tradition.

THE HAND AND ARM (below) may not accurately represent Mori Qafah's way of tying. But the knots (below) on the tefillin
should be in accordance with Mori Qafah--as they appeared in his edition of the Mishnah Torah- which appear to be a
demonstration of the way the Rambam tied as well.

Full Arm	Full Hand	Hand Knot	Head Knot	Upper Arm
Not Shown		or reversed		OR NO SPECIFIC WAY
	Last wrap around arm going to index finger is considered the seventh wrap. If you look underneath the arm and count, it is the seventh.
