The end of the thread is sometimes separated into a few thin strands or the thread was quite thick. Hence, Boojho found it difficult to pass a thread through the eye of a needle.

A yarn or a thread can be of different types according to their structure:

  • A single yarn is produced by twisting staple fibers together.
  • A ply yarn is produced by twisting two or more single yarns together.
  • A cord yarn is produced by twisting two or more ply or folded yarn.

[Extra information: Yarn is a long, continuous thread made of natural or synthetic fibres. Yarns are made up of thin strands called fibres. The process of making yarn from fibres is called spinning. In this process, a mass of cotton wool is drawn out and twisted.
