Niddy-noddy

Niddy-noddy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Niddy-noddy rather than just read about it. In short: A niddy-noddy is a tool used to make skeins from yarn. It consists of a central bar, with crossbars at each end, offset from each other by 90°.

Key takeaways

  • Niddy-noddy belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Niddy-noddy to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Niddy-noddy from memory before moving on to harder problems.

Reference excerpt

A niddy-noddy is a tool used to make skeins from yarn. It consists of a central bar, with crossbars at each end, offset from each other by 90°. The central bar is generally carved to make it easier to hold. Either one of the crossbars will have a flat edge to allow the skein to slide off, or will be completely removable. Niddy-noddies can be constructed of many different materials including wood, metal, and plastic. Wood is traditional, and most quality niddy-noddies are still made of wood. Budget spinners occasionally use niddy-noddies made from PVC pipes. Manufactured niddy-noddies can be made of different sizes, producing skeins from 12 inches in length to 4 feet in length. The most common size, however, produces a two-yard skein. Very small niddy-noddies are generally used for small samples. Many spinners will spin a sample length of yarn, ply it, and skein it using a niddy-noddy before washing. Then the spinner can see if the yarn is as desired or not. By counting the number of wraps for the skein, and measuring the length of one wrap, the approximate yardage can be calculated. The yardage is approximate because an exact yardage requires an even tension throughout wrapping the whole skein. Also, a very large skein requires wrapping the new layers on top of the old, which increases the length of the top layers. A niddy-noddy is held by the Christ Child in Leonardo da Vinci's Madonna of the Yarnwinder, owned by the Duke of Buccleuch and currently on loan to the Scottish National Gallery in Edinburgh.

Use

Generally yarn is skeined directly after spinning or plying. This is because after spinning or plying the yarn generally gets washed, and a skein is the best form to have the yarn in for washing. Although balls are easier for knitters and crocheters to use because they don't get tangled as easily, yarn is sometimes taken from a ball and reskeined in order to measure the yardage of leftover yarn, store it without tension, or to wash out kinks if the yarn was unraveled. When skeining from wheel spun yarn, the bobbin can either be removed from the wheel and placed on a lazy kate, or skeined directly from the wheel. If the bobbin is left on the wheel the tension on the drive band must be lessened in order to allow the bobbin to turn freely. Yarn spun on spindles can either be left on the spindle, or slipped onto a dowel for plying. The spindle or dowel is either placed in a lazy kate, or even a bowl to keep the spindle in one place while winding off the yarn. One end of the yarn is wound around the center piece and held firmly in place, while the rest of it is wrapped. The yarn is then taken over the left end of the top crossbar, down and under the right side of the lower crossbar, up and over the other end of the top crossbar, and then down and under the other end of the lower crossbar before returning to the starting point to complete one wrap. While rather awkward at first, one quickly picks up the rhythm. This process continues until the whole skein is wound. The time to skein yarn on a niddy-noddy depends on the yardage, and thus how many wraps need to be made. A larger niddy-noddy can speed up the skeining, but a very large one can be bulky, and thus slow down the time to do one wrap. At this point, the skein is secured by loose figure eight knots between each crossbar. This can be done with scrap yarn, or with slip knots from the end of the skein. In either case, loosely securing each end with a slip knot makes it easier to find the ends in the finished skein. Generally 4 or more knots are tied. Once the yarn has been skeined, it can be dyed or washed to set the twist. Weavers often dry their yarn under tension with a weight at the bottom of the loop, to stretch it out and remove some of the elasticity. Traditionally the niddy-noddy was used to the rhythm of a song, the opening line of which ran, ‘Niddy-noddy, niddy-noddy, two heads and one body.’

Other skein winders The closest tools similar to a niddy-noddy are the swift and the spinner's weasel. Some swifts need to be attached to a table, and even folding models tend to be a bit inconvenient to fold and carry, and thus are not as portable as a niddy-noddy. While swifts are useful for holding skeins for balling, they are not as convenient as niddy-noddies for winding skeins, nor are they as useful for calculating length, since expandable swifts don't wrap yarn tightly around a known circumference. The spinner's weasel is also not portable, but measures length more efficiently than a niddy-noddy and can be used while spinning.

Worked examples

Example 1 — a first encounter with Niddy-noddy

Start with the simplest possible case. Write down what Niddy-noddy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Niddy-noddy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Niddy-noddy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Niddy-noddy

In research
Niddy-noddy appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Niddy-noddy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Niddy-noddy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hand spinning tools, Yarn, so understanding it makes those chapters shorter.
In everyday life
Look for Niddy-noddy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
