For the dyed yarn to be woven, they need to be opened up. The bunch is wound on a small wooden charkhi which is put onto an axially rotating stick. One bunch on this charkhi rolls out many more bunches on another charkhi that are of lesser thread-count. Then the bunch is transferred on another charkhi, until single strands of cotton or silk are achieved. These single strands that have the dyed pattern are rolled on to a spindle using a charkha (spin-wheel) that is finally kept in ashuttle that the weaver uses to weave the fabric on the loom.
