A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole (or eye) at the other. The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance. High quality embroidery needles are plated with two-thirds platinum and one-third titanium alloy. Traditionally, needles have been kept in needle books or needlecases which have become objects of adornment. Sewing needles may also be kept in an etui, a small box that held needles and other items such as scissors, pencils and tweezers.
Sharp Needles: used for general hand sewing; built with a sharp point, a round eye, and are of medium length. Those with a double-eyes are able to carry two strands of thread while minimizing fabric friction.
Betweens or Quilting: These needles are shorter than sharps, with a small rounded eye and are used for making fine stitches on heavy fabrics such as in tailoring, quilt making and other detailed handwork; note that some manufacturers also distinguish between quilting needles and quilting between needles, the latter being slightly shorter and narrower than the former.
Needle size is denoted by one or more numbers on the manufacturer's packet. The general convention for sizing of needles, like that of wire gauges, is that within any given class of needle the length and thickness of a needle increases as the size number decreases. For example, a size 9 needle will be thicker and longer than a size 12 needle. However, the needle sizes are not standardized and so a size 10 of one class may be (and in some cases actually is) either thinner or finer than a size 12 of another type. Where a packet contains a needle count followed by two size numbers such as "20 Sharps 5/10" the second set of numbers correspond to the range of sizes of needle within the packet, in this case typically ten sharps needles of size 5 and ten of size 10 (for a total of 20 needles). As another example, a packet labeled "16 Milliners 3/9" would contain 16 milliners needles ranging in sizes from 3 to 9.
Native Americans were known to use sewing needles from natural sources. One such source, the agave plant, provided both the needle and the "thread." The agave leaf would be soaked for an extended period of time, leaving a pulp, long, stringy fibres and a sharp tip connecting the ends of the fibres. The "needle" is essentially what was the tip end of the leaf. Once the fibres dried, the fibres and "needle" could then be used to sew items together.
Sewing needles are an application of wire-making technology, which started to appear in the second millennium B.C. Some fine examples of Bronze Age gold torques are made of very consistent gold wire, which is more malleable than bronze. However, copper and bronze needles do not need to be as long: the eye can be made by turning the wire back on itself and redrawing it through the die.
The next major break-through in needle-making was the arrival of high-quality steel-making technology from China in the tenth century, principally in Spain in the form of the Catalan furnace, which soon extended to produce reasonably high quality steel in significant volumes. This technology later extended to Germany and France, although not significantly in England. England began creating needles in 1639 at Redditch, creating the drawn-wire technique still in common use today. About 1655, needle manufacturers were sufficiently independent to establish a Guild of Needlemakers in London, although Redditch remained the principal place of manufacture. In Japan, Hari-Kuyo, the Festival of Broken Needles, dates back to the 1600s.
