Arashi, meaning storm, is a technique in pole wrapped shibori.  The cloth is wrapped using a fine thread, pleated tightly, and then dyed on the pole.  I think of these pleated textiles as soft jewelry.

Bomaki, meaning pole wrapped, is a technique in shibori.  The china silk is wrapped using a fine thread, puckered tightly and then dyed on the pole.  The resulting exotic textile is very delicate and springy.
