Tying Tzitzith -
according to Nusach Ashkenazi
Position the techelet fringe so that the point where the blue meets white is at the aperature of the corner, with the white side joining the white on the left, and the techelet joining on the right.
At this point either make the Brachah or say the following:
"L'shem mitzvat tzitzit"
Note: According to all opinions, at the begining of the tying of the fourth corner, say the words "L'shem Mitzvat Tzitzith", as the tying of the fourth corner is the completion of the act, so if G-d forbid, your attention was diverted while you were tying the first three corners, make sure to have special intention for the fourth corner.
Now you are ready for your first of five sets of double knots, all which will be tied right over left, left over right, so that the left side remains stationary and the right side, the one with the techelet, goes back and forth around the left.
right over left ...
and left over right ...
... and tighten.
