This is a quick and easy process. Hold the fabric in the centre and allow the edges to drop down. Then starting at the top (centre) wrap string tightly around the cylinder shape and tie off at the end. The tighter you wrap and the thicker the binding thread the more resist there will be and this is what will create the radiating line in the dyed piece. I used quite a thin crotchet cord for this one. I think I will use a thicker binding if I do this again.
