Potter is to Clay as Weaver is to which of the following? Complete the analogy.

The relation is craftsman : the raw material he shapes with his hands. A potter works clay; a weaver works yarn. 'Cloth' is the strongest trap because it is what the weaver ends up with, not what he starts from — the potter's matching term would then be 'pot'. A loom is the frame he works at and a shuttle the small tool he throws across it, so both are equipment rather than material.
