Tekhelet Tying Diagram Series: Raavad by Mois Navon Ptil Tekhelet Organization

Notes:

1) A “Single White and Blue Cord Knot” is made by taking one white strand and one blue strand from the eight strands, then while holding them together, wrap them once around the remaining six strands and tucking in the ends in the wrap.

2) A “Chulya” is made by taking one white strand and one blue strand from the eight strands, then while holding them together, wrap them three times around the remaining six strands – start with white on top (closest to the garment). The final (seventh wrap) is made by dropping the blue strand from the “wrapping pair” and wind one more time using only the white strand. The “wrapping pair” strands are designated “Shamashim” and are used for all subsequent chulyot (though it is not halachically imperative that the same Shamashim be used).
