I often daven at Chabad shuls and I have noticed that they have some particulars regarding tallit usage inconsistent with the rest of Ashkenazi Jewry, including: not wearing when receiving an aliyah ...
A Lubavitch chasid wears his talis with the sides folded under, at the shoulders, bunching the side material under rather than over the material that lies on the shoulder (see an example). Why?
A Lubavitch chasid's talis gadol has a special way of being tied that ensures that the tzitzis hangs off of the side of the talis and not off of its front or back. Why?
