White Shadow shibori is one of the most difficult and time-consuming shape-resist techniques. It is difficult to get the threads pulled up tightly enough to prevent the indigo dye from bleeding in from behind and ruining the perfect white background. After each pattern has been stitched and pulled tightly, the back side of the piece is bound to a hard core (pole or rope). If there are any visible openings in the front of the piece they are plugged with cotton to prevent the dye from seeping in. The pieces below are examples of different techniques.
