These words mean to form a fabric from threads or other strands by various methods. Knit , crochet and tat are closely related in that all imply the drawing of a single strand of yearn, cotton, silk, etc., into series of interlocking loops. Knitting involves the use of two large, slightly pointed needles (for a knitting machine) on which a series of interlacing loops are made into successive rows, the fabric being transferred to alternate needles at the beginning of each new row of stitches. Crocheting is a type of knitting , but it is done with a single needle having a hook at one end. Unlike the stitches of knitting , those of crocheting are not necessarily made in successive rows. Both knit and crochet nearly always imply the direct construction of a garment or other article: to knit a sweater; to crochet a bedspread. Tat implies the making of an edging, as for a handkerchief, by means of a small hand shuttle that knots and loops a single thread into a lacelike strip that resembles crochet work.

Weave differs completely in principle from knit , crochet and tat . In weaving fabric, threads are entwined into a texture by interlacing on a loom two sets of strands, the warp and the weft (sometimes called woof) that are at right angles to each other. The warp threads, which run the long way of the fabric, are strung tightly on the loom; the weft threads are then passed back and forth, and over and under the warp by means of a shuttle. Weave is also used to describe the interlacing of straw and other pliable materials in making baskets, hats, etc.

To darn is to repair a hole in a garment or other cloth article by filling it in with yarn or thread, preferably by means of strands which are stitched across the hole and then filled in transverse threads in the manner of weaving .
