method for tying tekhelet?
The Arizal provided a method for tying white strings which is the basis for the popular 7,8,11,13 method of tying white strings. He also mentions that there are “chulyot”, upon which the Baal HaTanya derives the method of grouping the 7,8,11,13 wraps in to sets of three winds. The Radzyner Rebbi, adopted this method when using tekhelet, by requiring that one make the first wind and the last wind white and all the rest blue (as per one reading of the Gemara in Menachot). As such, it can be said that the “Arizal” method (as interpreted by the Baal Hatanya and the Radzyner) is as shown in my diagram entitled “Radzyn/Chabad”.
