Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.
The method of the Prophet (Sallallahu Alaihi wa Sallam) in wearing Imamah (Turban) was that he used to wrap his Imamah from under his chin and let it hang down on his backside between his shoulders.
Allah knows best.
