Internal wiring and Gilt options are available. Internal wiring is an enhancement which consists of a single silver wire passing thru the imame, so that it forms three external loops at the top and bottom onto which the thread and the tassel are easily attached. With internal wiring, you don't need to pass the thread thru the imame.
