Cotton is the most important of all plant fibres, used to make clothes.Cotton shirt can be prepared by following steps:

The making of cotton shirt is a long process. From cotton bolls, cotton is usually picked by hand. Fibres are then separated from the seeds by combing. This process is called ginning.
In spinning process, the fibres from a mass of cotton wool are drawn out and twisted. This brings the fibres together to form a yarn.
Weaving is binding of two sets of yarns at right angles to make a fabric. Weaving is done on looms. Now, on sewing this cotton fabric by needle, we get the cotton shirt.
