Weave, knit, crochet, braid, plait, tat mean to make a fabric or textile or to form an article by interlacing threads or strands of material.
Weave usually implies crossing rows of threads or strands interlaced into a web, irrespective of method, material, or pattern. Specifically the term means to interlace warp and weft yarns, by means of a loom, into a textile fabric, the yarns being passed over and under each other according to a predetermined pattern.
Knit implies the use of a single strand, commonly of yarn, to produce an elastic fabric and, in its specific sense, the use of two smooth-pointed needles alternately holding the material and forming a new row of interlacing loops.
Crochet specifically differs from knit by implying the use of a single hooked needle and in not necessarily suggesting a building up by successive rows.
Braid implies the entwining of three or more strands (as of hair, cord, or cloth strips) by passing one strand over another in such a manner that each strand winds a sinuous course through the ribbonlike or ropelike contexture that is thus produced.
Plait is sometimes identical in meaning with braid , but it tends to be used especially of the braiding of strands of hair or of the interlacing of straw or reeds (as in hatmaking or basketmaking) whether the method approaches that of braiding or weaving.
Tat implies the making of lace by the use of a single thread and of one or more shuttles by means of which a series of sliding knots and, usually, loops is formed in that thread.
