Loom waste: The amount or length of warp which necessarily cannot go into the fabric because it is used in tie-ins and in shed-making. The tie-up waste is variable, according to the habits of the weaver and the number of times the cloth is cut off the loom during the weaving of a single warp. The shed making waste may be considered as the distance from the back of the last threaded harness to the front of the reed in the beater's resting position, plus 8 inches

Low quarter: Third-to-lowest category in the blood system of grading wool
Low wheel: Same as flyer wheel; as opposed to high wheel
Luster: shine
Luster wools: Also known as Leicester wools. Wools from a variety of sheep breeds other than merino. The wools are long staple, 1 to 12 inches, with strong light relection and are used for tweeds

M

M's and O's: One of the balanced, texture contrast, linen weaves. The threading is based on contrasting arrangments of odds and evens, odds and odds, and evens and evens, so a true tabby cannot be produced
Madder: An ancient and very fast red dyestuff from the roots of the plant of the same name
Maidens: The vertical members that hold the flyer assembly on a flyer wheel
Maori weave: A textile technique characteristic of the Philippine Maoris. It is a twining technique, with two or more weft strands used simultaneously, worked on an untensioned, hanging warp with no shedding mechanism
Marche: English, Scotch, and Scandinavian term for lamm
McMorran Yarn Balance: a simple balance used to help determine the yards per pound of your handspun fiber
Medium wool: One of four categories of breeds of sheep, the fleeces of which have medium-coarse fibers
Medulla: The central core of air present in coarse wool fibers and hair fibers
Mercerized cotton: Cotton fiber that has been treated under tension with caustic alkali, resulting in a shiny surface and greater strength
Merino: A breed of sheep developed in Spain and yielding the very finest wool of any sheep
Metallic threads: Threads made of metals
Meter: A unit of length in the metric system, equal to 39.37 inches
Micron Count: One of three wool grading systems. Micron count is based on the average fiber diameter. The smaller the number, the finer/softer the fiber
Mohair: The long, silky fiber from the coat of the Angora goat
Mordant: Chemicals, usually acids or metallic salts, which combine with dyes on fibers to make more or less insoluble compounds
Mother-of-all: The horizontal member into which the maidens are set on a flyer wheel
Multiple harness loom: Literally would mean a loom with more than one harness. In actual usage, means a loom with more than 4 harness
Musk ox: Animal of the arctic regions of North America from which comes the extremely fine fiber called quivit

N

Nap: Surface of a fabric formed by fibers standing at an angle to the plane of the fabric
Napped cloth: A cloth on which a nap has been raised
Natural dyes: Dyes from natural sources (animal, vegetable, or mineral) as opposed to synthetic dyes
Naturals: Colors of fibers that are in their natural undyed state
Navajo loom: A stick loom suspended in a rigid vertical frame, used by the Navajo Indians
Navajo rug: The weft-face rug or blanket, usually of tapestry design, woven by Navajos on a Navajo loom, and characterized by selvedge on all four sides
Navajo saddle-blanket weave: The 4 harness, 3 color rotation weave which is older and more characteristic of the Navajos than the tapestry, but rarer. Diamon patterns are used and the weaving is done on primitive looms with heddle sticks
Navajo selvedge: The characteristic twisted cord edge formed around the continuous warp at the top and bottom edges of the weaving
Navajo sheep: A breed of sheep raised mainly on the reservation; has coarse-fibered fleece with little wool grease
Navajo spindle: The hand spindle used by Navajos and Hopis for handspinning wool, characterized by its large size, which necessitates rolling the shaft on the thigh to make it spin
Netting shuttle: A small wooden or plastic flat shuttle, pointed at one end and concave at the other, with a long tongue in the center for winding yarn. It is intended for knotted net making but some weavers like to use it in pick-up weaves
Niddy noddy: A two-ended T frame, with top and bottom Ts at right angles to each other, on which yarn is wound from a spinning wheel or spindle to make a skein
Noils: The short fibers that are removed from the long fibers in the combing of wool for worsted spinning
Nostepinne: A short baton used for winding center pull balls
Novelty yarn: A ply yarn in which the arrangement of the component parts is uneven in regular cycles, producing simple or fancy patterns in the yarn
Nub yarn: A ply yarn in which at regular intervals one yarn is twisted many times around the other to make a bunch. The bunch may be small or large. A second twisting operation is required, in which the binder yarn is twisted in the opposite direction to hold the bunches in place
Numerical count system: A system of grading the fineness of wool fibers according to numbers, which represent the number of hanks of yarn, each 560 yards long, that can be spun from one pound of wool. Numbers range from 30s to SOs, which is the very finest Merino
Nylon: The name of a large group of synthetic fibers of protein-like structure, noted for extreme toughness, strength and elasticity. The nylons wash easily, dry quickly, and are resistant to mildew and insects

O

Odds-and-evens: The progression of the twill threading, tie-up and treadling in which an odd numbered harness is always followed by an even numbered one, odds and evens combine in forming blocks or flats, and in treadle-lamm tie ups. All twill derivative weaves follow the odds and evens sytem, as well as twills
Oriental rugs: One piece, hand tied, knotted pile rugs. There are 6 types of oriental rugs, differing in place of production, type of knot, depth of pile, and type of color and design, but the history of oriental carpet is so long and confused and sujected to so many influences that even experts have difficulty in making identifications
Orion: A synthetic acrylic fiber which is warm, soft, resiliant, insensitive to moisture and has good wrinkle recovery
Overshot: A technique which is one of the twill derivative weaves and therefore has the basic characteristics of the 4 harness twill, but is interpreted to form 4-block patterns of great variety. Classically, the patterns have single color wool pattern weft on a white or natural background of cotton or linen
Oxford cloth: A cotton fabric woven in 2-2 basket weave
