Tapestry Versus Pattern Weaving
Tapestry and cloth weaving have less in common than their sharing of the word “weaving” would indicate. Both are indeed weaving and share the following characteristics: They rely on the interlacement of warp and weft; the warps (the threads that are attached to the loom) run parallel to each other; the weft (the threads that are woven into the warp run at right angles to the warp and inter-cross. But that is the extent of their relationship since the balance of these two very different weaves produces final products that are radically different from one another.
Cloth weaving can be either simple or complex but the resulting fabric is always somewhat balanced. By this I mean that the ratio of warp to weft is fairly even so that both show, possibly one more than the other, but still creating enough of a balance that the warp and weft are visible. Tapestry, on the other hand, is completely weft-faced. This means that the warp does not show at all. Just this difference alone is enough to set these weaves completely apart. A fabric that is completely weft-faced will be much stiffer than a balanced weave and, because the warp does not show and hence does not affect the appearance of the fabric, the application of the weft is all that counts in creating a design. The difference does not end here. Tapestry involves the use of discontinuous wefts. No given weft ever travels across the entire weaving (generally speaking), whereas in cloth weaving wefts generally do travel across the entire weaving.
Cloth weaving can produce stunning works of art intended for both decoration and clothing, but in general its purpose is to produce functional material. Tapestry has been used to create functional items such as rugs, saddle bags, and other items intended to be sturdy and withstand wear. But tapestry is most famous for the wall hangings created to decorate and insulate the walls of castles. Many different cultures have created tapestries and within those cultures certain techniques dominate, creating some confusion as to the difference, for example, among a Navajo rug and a European tapestry or a Coptic tapestry. The basis of all these tapestries is essentially the same since the warp is covered and the resulting fabric is pictorial and that design is based on the placement of the weft alone.
Although both cloth weaving and tapestry can theoretically be created on the same kind of loom, there are dedicated cloth and tapestry looms that provide certain elements to facilitate the proper weaving of each. A cloth loom does not require the same kind of tension that a tapestry loom does. However, more than two shafts (the movable parts of the loom that hold the heddles and allow for the raising and lowering of the warps in order to create a shed, which is simply a word to describe the space between these two sets of threads) is preferred for a cloth loom in order to produce the stunning possible number of weaving structures. Tapestry, on the other hand, requires a lot of tension but only two shafts (although some tapestry looms, such as Navajo looms, do not have any shafts but rather employ a more manual method for separating the threads). There are looms that will accomplish both cloth weaving and tapestry, but in general it is best to have looms devoted to one or the other. A cloth loom will generally not provide the necessary tension to weave tapestry and will potentially provide options that are not at all necessary for tapestry. A good analogy would be the mountain bike versus a road bike. You can ride a mountain bike on the road but it’s a lot more efficient and faster to ride a road bike on a road. It’s nearly impossible to ride a road bike on a dirt trail. If you intend to do both with passion you are best off owning both kinds of bikes.
I find that the personality that loves tapestry does not necessarily love cloth weaving. I am of that ilk. The same applies in the opposite direction. Cloth weavers are able to patiently set up their looms over the course of hours and days and then quickly weave yards and yards of cloth. Tapestry looms are relatively quickly set up but the weaving takes a very long time. The relative nature of a cloth weaving is predetermined by the threading of the warp. Certain elements can be modified, of course, by the shedding pattern (which warps are raised) and the choice of weft, but since the warp shows its color and threading cannot be changed during the course of weaving, the major elements of a cloth weaving are set in place when you warp the loom. Since the tapestry warp is completely covered by the weft, it can only effect the tapestry by its set (how close or far apart the warps are spaced) and the size of the warp. The warp has to be in correct relationship to the weft so that the tapestry remains weft-faced.
Tapestry is like painting. The warp creates a canvas on which one paints with fiber. But unlike painting, the final and necessary structure of the “canvas” is only created once the weft is applied. Hence, tapestry becomes a very architectural kind of artwork since the structure is created from the bottom up. What was woven at the beginning cannot be changed after the fact. One does not have the luxury of the whole page to play with since the page only exists in the tapestry as the “paint” is applied. It’s an interesting constraint that can create as many mistakes as accidental successes. But whereas tapestry is like painting, it is also still weaving and hence takes its own unique place in the world of art.
