Fig 1: We begin by doing a long tailed daisy with the start point on A. The loop is angled at about 45 degrees since we are making a zig zag pattern.
While making the ‘tail’, before going in through the fabric, we wrap the thread around the needle as shown in the illustration.

Fig 2: Then, the needle is put in through C and brought out through D, again at an angle of about 45 degrees.
Next , loop the thread around the needle as shown. This is to make the next long tailed daisy.
