Thickset.—One of the many varieties of Fustian, which comprise Corduroys, Velveteens, Moleskins, Thickset, etc.

Thread.—In general, a twisted strand of cotton, flax, wool, silk, etc., spun out to considerable length is called thread. In a specific sense, thread is a compound cord consisting of two or more yarns firmly united together by twisting. Thread made of silk is technically known as sewing thread; that made of flax is known as linen thread; while cotton thread intended for sewing is commonly called spool cotton. These distinctions are generally observed by the trade.
