In knitting, crochet and other handmade textile arts, blocking is a final stage of handmade textile production that adjusts the shape and size of the finished piece. Not all pieces need blocking; however, blocking is standard for lace work and is not uncommon in sweaters, socks, and other solid projects. Through heat and moisture, blocking sets the stitches and standardizes the final dimensions, and may enhance the drape. [1] [2] Hand manufacture places natural stresses on fabrics that may result in deviations from its intended shape and size. Blocking is only effective on natural fibres [3] but a technique called killing may be used on synthetic fibres to achieve an effect similar to blocking.
The degree of malleability is determined by the type of yarn used, with wool providing the most flexibility. For projects that are produced in sections or piecework, blocking is normally done prior to final assembly, and may be repeated after final construction.
Blocking can be done in several different ways. Depending on the method, the crafter may use rustproof pins, blocking wires, blocking combs, wool wash, a wash basing or sink, a spray bottle, a steamer, or a steam iron [4] [2] . A stable flat surface, measuring tape, and towels are standard and some prefer to also use blocking mats or a blocking board. [4] Handmade socks are typically blocked on sock blockers. [4] Fibres that tolerate water well may be wet blocked, shaping moist fabric into the desired shape and then allowing it to air dry. Cold (or spray blocking) blocking (or spray blocking) uses no heat and less water to achieve the same result by spraying water upon the material instead of immersing the fabric. Steam blocking uses a steamer or steam iron, but without applying direct pressure to the item. [5]
Wet blocking is done by saturating a garment in warm water and allowing it to dry. Some items (especially lace) are stretched while wet with the use of pins and/or blocking wires, while others may be gently shaped without stretching.
Steam blocking is done by hovering a hot, steaming iron over the fabric. Hovering the iron about 1 or 2 inches above the fabric flattens the stitch, makes it thinner, and allows it to hold its shape better. This is the only method that works for blocking synthetics, like acrylic.
Spritz blocking involves spraying the garment with water. This relaxes the fibres more than steam blocking but less than wet blocking. Most often, a spray bottle is used.
Sock blocking involves wetting the garment using wet or spray blocking techniques with water. The socks are then placed on sock blockers, which should be sized to match the finished sock dimensions. The blockers are then left to dry flat or hung up on a hook. [4]
It is possible to set synthetic fibres through a process known as "killing", wherein the item is pinned in place and carefully steamed to achieve a very slight controlled melt of the fibres. Killed fabrics are permanently set and cannot be returned to their original form through washing.
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 crochet, meaning 'hook'. Hooks can be made from a variety of materials, such as metal, wood, bamboo, bone or 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.
Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses. Although yarn may be dyed different colours, most yarns are solid coloured with a uniform hue.
Tunisian crochet or Afghan crochet is a type of crochet that uses an elongated hook, often with a stopper on the handle end, called an Afghan hook. It is sometimes considered to be a mixture of crocheting and knitting. As such, some techniques used in knitting are also applicable in Tunisian crochet. One example is the intarsia method.
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.
Knitting is the process of using two or more needles to pull and loop yarn into a series of interconnected loops in order to create a finished garment or some other type of fabric. The word is derived from knot, thought to originate from the Dutch verb knutten, which is similar to the Old English cnyttan, "to knot". Its origins lie in the basic human need for clothing for protection against the elements. More recently, hand knitting has become less a necessary skill and more of a hobby.
Nålebinding is a fabric creation technique predating both knitting and crochet. Also known in English as "knotless netting", "knotless knitting", or "single-needle knitting", the technique is distinct from crochet in that it involves passing the full length of the working thread through each loop, unlike crochet where the work is formed only of loops, never involving the free end. It also differs from knitting in that lengths must be pieced together during the process of nålebinding, rather than a continuous strand of yarn that can easily be pulled out. Archaeological specimens of fabric made by nålebinding can be difficult to distinguish from knitted fabric.
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
A knitting machine is a device used to create knitted fabrics in a semi or fully automated fashion. There are numerous types of knitting machines, ranging from simple spool or board templates with no moving parts to highly complex mechanisms controlled by electronics. All, however, produce various types of knitted fabrics, usually either flat or tubular, and of varying degrees of complexity. Pattern stitches can be selected by hand manipulation of the needles, push-buttons and dials, mechanical punch cards, or electronic pattern reading devices and computers.
Lace knitting is a style of knitting characterized by stable "holes" in the fabric arranged with consideration of aesthetic value. Lace is sometimes considered the pinnacle of knitting, because of its complexity and because woven fabrics cannot easily be made to have holes. Famous examples include the Orenburg shawl and the wedding ring shawl of Shetland knitting, a shawl so fine that it could be drawn through a wedding ring. Shetland knitted lace became extremely popular in Victorian England when Queen Victoria became a Shetland lace enthusiast. Her enthusiasm resulted i.a. in her choosing knitted lacework for presents; e.g. when in ca. 1897 the Queen gave a lace shawl as a present to American abolitionist Harriet Tubman. From there, knitting patterns for the shawls were printed in English women's magazines where they were copied in Iceland with single ply wool.
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.
Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. Some linens, wools to be woven into tweed, and the uneven filaments of some types of silk are allowed to retain their normal irregularities, producing the characteristic uneven surface of the finished fabric. Man-made fibres, which can be modified during production, are especially adaptable for special effects such as crimping and texturizing.
A granny square is a piece of square fabric produced in crochet by working in rounds from the center outward. Granny squares are traditionally handmade as crochet and cannot be manufactured by machine. They resemble coarse lace. Although there is no theoretical limit to the maximum size of a granny square, crocheters usually create multiple small squares and assemble the pieces to make clothing, purses, Afghan blankets, and other household textiles.
In crochet, a stitch marker is a mnemonic device used to distinguish important locations on a work in progress. Crochet patterns have a mathematical basis, so stitch markers serve as a visual reference that takes the place of continuous stitch counting and reduces a crocheter's error rate.
A hook gauge or needle gauge is a measuring device used by crocheters and knitters to test the sizes of particular crochet hooks and knitting needles. Hook gauges are usually made of plastic or aluminum and have sizing holes from 2mm to 11mm diameter. A hook gauge also functions as a ruler to test the size of a test swatch of handmade fabric.
Hand knitting is a form of knitting, in which the knitted fabric is produced by hand using needles.
Textile manufacturing is one of the oldest human activities. The oldest known textiles date back to about 5000 B.C. In order to make textiles, the first requirement is a source of fibre from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving to create cloth. The machine used for weaving is the loom. Cloth is finished by what are described as wet process to become fabric. The fabric may be dyed, printed or decorated by embroidering with coloured yarns.
Cowichan knitting is a form of knitting characteristic of the Cowichan people of southeastern Vancouver Island, British Columbia. The distinctively patterned, heavy-knit Cowichan sweaters, popular among British Columbians and tourists, are produced using this method. Cowichan knitting is an acculturated art form, a combination of European textile techniques and Salish spinning and weaving methods. From this union, new tools, techniques and designs developed over the years.
Sewing is the craft of fastening or attaching objects using stitches made with needle and thread. Sewing is one of the oldest of the textile arts, arising in the Paleolithic Era. Although usually associated with clothing and household linens, sewing is used in a variety of crafts and industries, including shoemaking, upholstery, sailmaking, bookbinding and the manufacturing of some kinds of sporting goods. Sewing is the fundamental process underlying a variety of textile arts and crafts, including embroidery, tapestry, quilting, appliqué and patchwork.
