How are the Tzitzit tied?
Tying Tzitzit is a Jewish art, a form of macrame. A hole is carefully made and reinforced in each corner of the tallit. Through each hole, four strands are inserted: three short strands and one long strand. The longer stranded is called the shammash and this is the one which is used for winding around the others. To tie the Tzitzit, line up the four stands so that the three of equal length are doubled evenly, and the four strand is lined up at one end with the other seven ends. With four strands in one hand, and the other four in the other, make a double knot at the edge of the fabric. Then take the shammash and wind it around the other seven strands seven times in a spiral motion. Make a second double knot, with four strands in one hand and four strands in the other. Then wind the shammash around the seven strands eight times and make another double knot. Wind the shammash around eleven times and make a double knot. Finally, wind the shammash thirteen times around the remaining seven
