As quoted from:
Shulchan HaMelech, a Kitzur Shulchan Aruch in 3 volumes as compiled by Maharan HaRav Shmuel Laniado z'al, 1923 with the supplement "Al HaShulchan" containing various opinions compiled by Ezra Basri, Chief Justice of the District Court, Jerusalem in 1992.
We would also like to dedicate this learning for the speedy and complete recovery of our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia. Please have him in mind when studying.
p. 29 Chapter Nine Al HaShulchan3. There is no need to place a mark or band on one of the edges of a tallit so as not to put it on the wrong way round as some have the custom to do since the Ari Zal states explicitly that one does not have to be careful about this, and one can wear it whichever way round it comes into one's hands. (Ben Ish Chai Bereshit 8)
