Tekhelet Tying Diagram Series: The 7-8-11-13 Method by Mois Navon Ptil Tekhelet Organization

Notes:

1) A “Single Knot” is made by taking the four strands from one side of the garment and the opposing four strands from the other side of the garment and tying a simple knot.

2) The initial wrap of 7 winds is made by taking one white strand from the total of eight strands and wrapping it around the remaining seven strands once. This “wrapping” strand is designated the white “Shamash” and is used for the subsequent white wrap at the end (though it is not halachically imperative that the same Shamash be used). The remaining six winds are made taking one blue strand and wrapping it around the remaining seven strands six times. This “wrapping” strand is designated the tekhelet “Shamash” and is used for all subsequent blue wraps (though it is not halachically imperative that the same Shamash be used).

3) The eight winds are made by wrapping the tekhelet shamash eight times around the core strings; the eleven winds are made by wrapping the tekhelet shamash eleven times around the core strings.

4) The thirteen winds are made by wrapping the tekhelet shamash twelve times and then wrapping the white shamash once.
