מנחות דף לט עמוד א, ד”ה לא יפחות לפי שתכלת דומה לים וים דומה לרקיע ואנן דלית לן תכלת לא קפדינן בהא והא נמי דאמרינן צריך לקשור על כל חוליא וחוליא היינו כדי שיהא ניכר התכלת ומה שאנו נוהגים חמשה קשרים פירש בקונטרס גבי ציצית שקולה כנגד כל המצות לפי שציצית עולה ת”ר וח’ חוטין…

This uses a variation of Raavad tying. It’s al pi Kabbala 7-7-7-7 but the second chulya is all white, since the Techeiles ones are Domeh L’Rakia/Shamayim, and the remainder makes it add up to 28 which has some Koach. Some Yemenite Jews will also do 28 (even though 26 is YKVK) since there is some…

It has 13 chulyot but can also be 7, and generally alternates white and Tekhelet between them, starting and ending with a chulyah of white. Those chulyot are distributed between five (double) knots with two chulyot between the top four knots…
