Two or more straight pins, or needles, as they are often called, of steel, wood, ivory, bone, or vulcanite. The steel pins are used for fine work, and the other kinds when coarser material is used. With the knitting-pins, one continuous thread of either wool, silk, cotton, linen thread, etc., is worked to form a series of loops on each needle by passing the thread round the needle and drawing it through the previously made loop. Each stich made is slipped off, and left hanging free. When one row is complete, a second is worked in a similar way.
