Sewing allows you to make clothes. You need two items to be able to sew: a
needle and some material. If you are in the tailor shop, you can also dye the
clothes a certain colour during the sewing process. The higher skill you have
the better clothes you will make. The material you are going to sew must be on
the ground.
Syntax:  use sewing at <material> make <type> [dye <color>].
For a list of types:   use sewing at types
You can also 'use sewing at cotton cloth' if you have picked cotton balls.
