Crochet is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread, or strands of other materials. The name is derived from the French term croc, which means 'hook'. Hooks can be made from a variety of materials, such as metal, wood, bamboo, bone or even plastic. The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one is begun, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and broomstick lace, do keep multiple crochet stitches open at a time.
Knitting is a method for production of textile fabrics by interlacing yarn loops with loops of the same or other yarns. It is used to create many types of garments. Knitting may be done by hand or by machine.
A knitting needle or knitting pin is a tool in hand-knitting to produce knitted fabrics. They generally have a long shaft and taper at their end, but they are not nearly as sharp as sewing needles. Their purpose is two-fold. The long shaft holds the active (unsecured) stitches of the fabric, to prevent them from unravelling, whereas the tapered ends are used to form new stitches. Most commonly, a new stitch is formed by inserting the tapered end through an active stitch, catching a loop of fresh yarn and drawing it through the stitch; this secures the initial stitch and forms a new active stitch in its place. In specialized forms of knitting the needle may be passed between active stitches being held on another needle, or indeed between/through inactive stitches that have been knit previously.
A stocking frame was a mechanical knitting machine used in the textiles industry. It was invented by William Lee of Calverton near Nottingham in 1589. Its use, known traditionally as framework knitting, was the first major stage in the mechanisation of the textile industry, and played an important part in the early history of the Industrial Revolution. It was adapted to knit cotton and to do ribbing, and by 1800 had been adapted as a lace making machine.
The term "gauge" is used in knitting to describe the fineness size of knitting machines. It is used in both hand knitting and machine knitting. The phrase in both instances refers to the number of stitches per inch rather than the size of the finished article of clothing. The gauge is calculated by counting the stitches or needles across a number of inches, then dividing by the sample's width in inches.
Combined knitting or combination knitting is a knitting method that combines elements of Eastern-style knitting with the Western techniques. The name was suggested by Mary Thomas in her 1938 book "Mary Thomas's Knitting Book", where she described the method as "..the better way to work in Flat Knitting. The resulting fabric is more even and closer in construction." By wrapping the yarn the opposite way while purling, the knitter changes the orientation of the resulting loops; then the next row's knit stitches can be formed by inserting the needle through the back leg, rather than through the front leg, without twisting the stitch. This method is suitable for all knitted fabrics from the basic Stockinette stitch, to any other technique, such as Fair Isle, circular knitting, or lace knitting.
Slip-stitch knitting is a family of knitting techniques that uses slip stitches to make multiple fabrics simultaneously, to make extra-long stitches, and/or to carry over colors from an earlier row.
In knitting, an increase is the creation of one or more new stitches, which may be done by various methods that create distinctive effects in the fabric. Most knitting increases either lean towards the left or the right.
In knitting, casting on is a family of techniques for adding new stitches that do not depend on earlier stitches, i.e., having an independent lower edge. In principle, it is the opposite of binding off, but the techniques involved are generally unrelated.
Knitting abbreviations are often used for brevity in describing knitting patterns.
In knitting, welting is the horizontal analog of ribbing; that is, one or more horizontal rows of knit stitches alternating with one or more rows of purl stitches.
In knitting, a plaited stitch, also known as a twisted stitch, is a single knitted stitch that is twisted clockwise or counterclockwise, usually by one half-turn (180°) but sometimes by a full turn (360°) or more.
Basic knitted fabrics include stocking stitch, reverse stocking stitch, garter stitch, seed stitch, faggoting, and tricot. In some cases, these fabrics appear differently on the right side than on the wrong side.
Flat knitting is a method for producing knitted fabrics in which the work is turned periodically; that is, the fabric is worked with alternating sides facing the knitter. Another method of achieving the same result is to knit alternately from right to left and left to right without turning; this back-and-forth technique requires either innate or learned ambidextrous motor skills. The two sides of the fabric are usually designated as the right side and the wrong side.
In knitting, picking up stitches means adding stitches to the knitting needle that were previously bound off or belong to the selvage.
Double knitting is a form of hand knitting in which two fabrics are knitted simultaneously on one pair of needles. The fabrics may be inseparable, as in interlock knitted fabrics, or they can simply be two unconnected fabrics. In principle, an arbitrary number of fabrics can be knitted simultaneously on one pair of knitting needles with yarns, as long as one is careful.
Knitted fabric is a textile that results from knitting, the process of inter-looping of yarns or inter-meshing of loops. Its properties are distinct from woven fabric in that it is more flexible and can be more readily constructed into smaller pieces, making it ideal for socks and hats.
A selvage or selvedge is a "self-finished" edge of a piece of fabric which keeps it from unraveling and fraying. The term "self-finished" means that the edge does not require additional finishing work, such as hem or bias tape, to prevent fraying.
Hand knitting is a form of knitting, in which the knitted fabric is produced by hand using needles.
Illusion knitting or shadow knitting is a form of textile art, in which the knitting is viewed as simply narrow stripes from one angle, and as an image when viewed from another angle. Illusion knitting has been recognised as an art form since 2010, largely due to the advances made by Steve Plummer who has created several large and detailed pieces. Similar effects occur in Tunisian crochet.
