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. [1] 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.
Illusion knitting uses two colours of yarn and is worked in stripes of two rows in each colour. Illusion knitting is based on the flat smooth stocking stitch and the raised garter stitch. It is this combination of textures which allows the image to be seen only from the proper angle.
Traditionally, charts for illusion knitting use four rows of knitting symbols to represent the stitches which the designer wishes to be seen. This makes the charts elongated and difficult to use for anything other than simple blocks of colour. These four rows make up two pairs where, in most cases, one pair is considered the opposite of the other. Where one pair has two rows of knit stitches, the other image pair has both knit and purl stitches.
As in mosaic knitting, the knitter alternates between two colors. Colors with good contrast are preferred but are not required. The knitter knits two rows of color A, then two rows of color B, and repeats this throughout the body of the work. Only knit or purl stitches are used.
Each row in the pattern, shown in the thumbnail to the right, represents four rows of knit or purl stitches, and each column represents one stitch. To follow this pattern, a knitter would use black and white: white being the background color (BC), and black being the master color (MC).
The visual effect of shadow knitting is due to the different height of the knit stitches on the wrong side rows. A knit stitch is flat, while a purl stitch is raised. Therefore, one can change which color (dark or light) stands out by changing from knit to purl. So the basic idea is to create a pattern in knit stitches in the colors one wants and purl stitches in the background color. When looking straight at the knitted piece, the stitches look approximately the same, but from an angle, only the raised purl stitches are visible.
There are no constraints on the position of the purl/knit stitches, so a nearly infinite variety of patterns can be made. The pattern will not be apparent from every direction of viewing, since one ridge may "overshadow" another. Knitters often enjoy watching when the picture created becomes visible. The stark contrast of alternating light and dark stripes is also visually interesting.
Extensions of the method include using more than two colors or using other stitches; e.g., lace knitting or cable knitting.
For an illusion artwork to be effective it has to be able to be seen from a variety of angles. Generally, illusions that are designed to be viewed from the side are best. If the illusion hangs on the wall you can move around it and see the image appear and disappear. The illusion can be viewed equally well from the right and wrong sides. An illusion designed to be seen from the bottom would have to hang very high on the wall as you would probably never be able to see it from facing it directly. This type of illusion is best used on a flat surface.
Steve Plummer is a knitting artist who previously specialised in knitting wall-hangings and other items, primarily for the teaching of Mathematics. He approached illusion knitting from a mathematician's point of view and started to use a different method of charting.
These charts use a square grid and are created by laying the grid over an existing image then colouring in all the stitches that need to be seen as raised bumps. Throughout the charting process it is still possible to see the original image and there is no distortion. These charts are different because they allow the four rows of the traditional method to be condensed into two different rows of squares. They can be used for creating very simple images, if required, but also allow much more flexibility to create works of art. The old method allowed areas to show either light or dark; the new method allows for intermediate shading, still using just two colours and only one colour in each stripe. The amount of shading depends on the number of stitches that are raised compared to the number that are lowered.
Some of Steve's illusions are quite large. His Mona Lisa is significantly bigger than the real thing. The size is dictated by the smallest detail he wants to see, which, in a portrait, may be the centre of the eye. This then has to become one raised bump (garter stitch) on the knitting and the ridge in front of it must lie flat so you can see over it (stocking stitch). The rest of the image is built around this detail.
The charting process takes perseverance, time and an amount of three-dimensional awareness. A chart can take up to 100 hours to produce. It is a process that can be learned by people with a little artistic ability and a lot of patience.
It is possible to combine illusion knitting with other textile techniques. Those listed below have been used successfully. There are probably many other possibilities.
Illusion Art does not have to be pictorial. It also lends itself to geometric works. Sometimes the same illusion can be created in different ways. It is much less successful for abstract art. The brain needs to be able to perceive an image and fill in the gaps, which would be extremely difficult with an abstract design.
Illusion Knitting Art is very new, the earliest exhibitions being held in 2010.
Artists working in this field include Steve Plummer, Pat Ashforth, Brent Annable, Tanja Boukal, Nelleke Kool, Julie Rosencrans, Lisa Lehner and George Maffett. Some of these artists have experimented with using computer programs to speed up the design process. So far, no program has been as good as the artist's eye. George Maffett uses a Lego 3-D modelling program to assist in the process.[ citation needed ]
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.
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.
Fair Isle (/fɛəraɪ̯l/) is a traditional knitting technique used to create patterns with multiple colours. It is named after Fair Isle, one of the Shetland Islands. Fair Isle knitting gained considerable popularity when the Prince of Wales wore Fair Isle jumpers in public in 1921. Traditional Fair Isle patterns have a limited palette of five or so colours, use only two colours per row, are worked in the round, and limit the length of a run of any particular colour.
Intarsia is a knitting technique used to create patterns with multiple colours. As with the woodworking technique of the same name, fields of different colours and materials appear to be inlaid in one another, fit together like a jigsaw puzzle.
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.
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.
Entrelac is a knitting technique used to create a textured diamond pattern. While the result resembles basket-woven strips of knitted fabric, the actual material comprises interconnected squares on two different orientations.
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.
In knitting, binding off, or casting off, is a family of techniques for ending a column of stitches. Binding off is typically used to define the final edge of a knitted fabric, although it may also be used in other contexts, e.g., in making button holes. In principle, binding off is the opposite of casting on, but the techniques are generally not mirror images of one another. Sometimes, however, they can produce a mirror image appearance.
Brioche knitting is a family of knitting patterns involving tucked stitches, i.e., yarn overs that are knitted together with a slipped stitch from the previous row. Such stitches may also be made by knitting into the row below and dropping the stitch above.
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.
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.
Hand knitting is a form of knitting, in which the knitted fabric is produced by hand using needles.
A knitting pattern is a set of written instructions on how to construct items using knitting.
Twined knitting is a traditional Scandinavian knitting technique. It refers to knitting where two strands of yarn are knitted into the fabric alternatively and twisted once and always in the same direction before every stitch. The technique is called tvåändsstickning in Swedish, tvebandsstrikking in Norwegian, and tvebinding in Danish. Their literal meaning is "two-end knitting", referring to the traditional way of knitting with both yarn ends from one ball of yarn.
