Part of Textiles and Weaving
Spinning converts prepared fiber into yarn by twisting individual fibers together so they grip each other under tension. The resulting yarn is stronger than any individual fiber, flexible enough to weave or knit, and can be produced from dozens of different plant and animal materials using tools that range from a weighted stick to a sophisticated wheel. Spinning is arguably the most fundamental textile skill — without yarn, there is no fabric.
The Physics of Spinning
Twist is everything. When fibers are twisted together, the helical arrangement causes each fiber to be gripped by its neighbors. The tighter the twist, the stronger the grip — but too much twist makes yarn brittle and kinked. Too little twist and the fibers slide apart under tension.
Twist direction matters for how yarns interact:
- S-twist: twist spirals like the center of an “S” — counterclockwise when viewed from above
- Z-twist: twist spirals like the center of a “Z” — clockwise when viewed from above
Most hand spinners spin Z-twist singles. When plying (combining two or more singles), you twist in the opposite direction (S) so the plying twist locks the singles together rather than untwisting them.
Twist per inch (TPI): Fine yarns need more twist per inch; coarse yarns need less. A fine linen thread might have 20–30 TPI; a thick rug yarn might have 4–6 TPI. The fiber itself tells you when it has enough twist: draft (pull) a length of yarn and if the fibers hold together under light tension without slipping, twist is sufficient.
The Drop Spindle
The drop spindle is the oldest and simplest spinning tool — a stick with a weighted whorl (disc) that spins freely. It requires no machinery and can be made from a straight stick and a carved disc of wood, bone, or clay in an afternoon.
Spindle Construction
Stick: 25–35 cm long, 6–10 mm diameter. Straight-grained hardwood is best. Taper one end to a point. Cut a notch near the top end, or carve a small hook, to catch the yarn.
Whorl: A disc with a center hole, 5–10 cm diameter, 1–2 cm thick. Weight 30–80 grams total for the complete spindle. Lighter whorls (30–40 g) spin faster and suit fine fibers; heavier whorls (60–80 g) spin slower and are better for coarse fibers and beginners.
The whorl can be:
- Carved wood (dense hardwood for best balance)
- Fired clay (model a disc, pierce with the stick before firing)
- Stone with a drilled hole
- A large button, a potato (temporary), or a thick wooden wheel cut from a branch
Balance matters more than weight alone. An off-center whorl wobbles, twists unevenly, and is exhausting to use. Test balance by spinning the whorl flat on a table — it should spin smoothly without wobbling.
Supported vs. Drop Spinning
Drop spinning (spindle hangs in air): The weight of the spindle provides tension as it hangs. This is more efficient but requires more coordination initially.
Supported spinning (spindle rests in a bowl or on the ground): Easier to learn; good for very fine, delicate fibers that would break under the weight of a hanging spindle. Used in parts of India for fine cotton and in the Andes for alpaca.
Spinning Technique (Drop Spindle)
-
Attach a leader: Tie 30–40 cm of existing yarn (or a piece of cord) to the shaft below the whorl. Wrap it around the shaft several times, bring it up and over the whorl edge, then hook it through the notch at the top. This gives the new fiber something to join onto.
-
Join fiber to leader: Hold the leader end and overlap the prepared fiber (rolag or sliver end) with it. Twist slightly with your fingers to join.
-
Draft and spin: Hold the fiber supply in your non-dominant hand (the “fiber hand”). With your dominant hand, give the spindle a clockwise spin (for Z-twist). As it spins, use your fiber hand to pinch the fiber just above the forming yarn and your other hand to draft (pull) fiber out below the pinch. The spinning spindle twists the drafted fiber into yarn.
-
Pinch, draft, release: This three-beat motion is the core of all spinning. Pinch to stop twist from running into the fiber supply. Draft to pull out a thin even length of fiber. Release the pinch to let twist run into the drafted fiber, forming yarn.
-
Wind on: When the spindle nears the floor, unhook the yarn from the notch, wind the spun yarn onto the shaft in a cone shape (called a cop), re-hook, and continue.
Common Mistakes
| Problem | Cause | Fix |
|---|---|---|
| Yarn breaks | Too little twist, or drafting too fast | Spin more before drafting; slow down |
| Yarn too thick and lumpy | Drafting unevenly | Draft a thinner, more consistent amount |
| Yarn over-twisted, kinks | Too much twist | Draft more quickly or reduce spin |
| Spindle falls and rolls | Yarn caught wrong in notch | Check hook/notch; re-attach leader |
| Yarn joins to leader poorly | Insufficient overlap | Use 5–8 cm overlap; add more twist at join |
The Spinning Wheel
A spinning wheel automates twist insertion via a drive wheel connected to a smaller whorl by a drive band. The spinner drafts fiber; the wheel inserts twist continuously. Wheel speeds up spinning dramatically — a skilled wheel spinner can produce yarn 5–10x faster than a skilled drop-spindle spinner.
Wheel Types
Great wheel (walking wheel): Simplest mechanism. Large drive wheel (1–1.5 m diameter) connected directly to a spike (spindle) via a drive band. No flyer or bobbin — the spinner walks backward drafting fiber, then walks forward to wind yarn onto the spindle. Excellent for coarse wool and cotton. Can be built with basic carpentry.
Flyer wheel (Saxony wheel, treadle wheel): More complex mechanism with a treadle (foot pedal) that turns the drive wheel, which drives a flyer and bobbin assembly. The flyer rotates faster than the bobbin, which winds yarn automatically while spinning continues. Allows seated, continuous spinning. Requires more skill to build and maintain.
Charkha: Small box loom used for cotton spinning, common in South Asia. Hand-cranked. Extremely portable and efficient for short-staple plant fibers.
Drive Ratio and Speed
The ratio of drive wheel diameter to whorl diameter determines how many times the spindle rotates per wheel revolution. A 60 cm drive wheel with a 3 cm whorl gives a 20:1 ratio — 20 spindle rotations per wheel turn. Higher ratios insert twist faster and suit finer fibers.
Plying
A single strand of spun yarn (a “single”) has residual twist energy and will kink when relaxed. Plying — twisting two or more singles together in the opposite direction — balances this energy and produces a balanced, stable yarn.
Two-ply: Most common. Wind two singles onto separate bobbins or balls. Hold together and spin in the opposite direction from the original twist (if singles are Z-twist, ply with S-twist). Ply until the yarn hangs straight without kinking when relaxed.
Three-ply: Stronger and rounder than two-ply. Used for sewing thread, warp yarn, and rope.
Cable yarn: Ply two two-ply yarns together (twist direction alternates again). Produces very strong, round yarn for ropes, rugs, and industrial cordage.
Measuring Yarn
Wraps per inch (WPI): Wind yarn around a ruler for 1 inch without gaps or overlaps. Count wraps. This determines how fine or coarse the yarn is:
| WPI | Yarn Weight | Uses |
|---|---|---|
| 30+ | Lace | Fine shawls, linen thread |
| 20–30 | Fingering | Socks, fine garments |
| 14–20 | Sport/DK | Sweaters, medium fabric |
| 10–14 | Worsted | General weaving, heavy garments |
| 6–10 | Bulky | Outerwear, blankets |
| Under 6 | Super bulky | Rugs, braided goods |
Yards per pound (ypp): A standard skein is 1,600 ypp for worsted-weight yarn. Finer yarn has more ypp; coarser has less.
Finishing Spun Yarn
Raw yarn (off the spindle) is not finished. It contains uneven twist and stress from winding. Setting the twist produces stable, consistent yarn.
Skeining: Wind yarn off the bobbin or spindle onto a niddy-noddy (two-bar stick used to wind skeins of consistent size) or around a chair back. Tie loosely in 4 places with scrap yarn so the skein doesn’t tangle.
Washing: Immerse the skein in hot water (no agitation) for 10–15 minutes. Press out water gently.
Thwacking: Snap the wet skein against a hard surface (chair back, table edge) 3–5 times. This fulls the fiber slightly and evens out twist distribution.
Drying under tension: Hang the skein with a light weight attached (a stone, a wooden dowel) while drying. This sets the twist straight and prevents kinking.
Fiber-Specific Spinning Notes
Wool: Most forgiving fiber to learn on. Enough natural crimp and scales to grip easily. Spin “in the grease” (lanolin still present) for ease; wash after spinning.
Cotton: Short staple requires a supported spindle or charkha. Spin very slowly with a high-ratio spindle. Cotton has no natural crimp so needs more twist than wool to hold together.
Flax/Linen: Spin wet — keep a bowl of water nearby and wet your fingers frequently. Wet flax drafts smoothly; dry flax is stiff and breaks. Spin from the distaff (a stick or frame holding prepared flax upright) for continuous drafting.
Nettle: Similar to flax. Tends to be coarser. Good for rope and heavy-duty fabric.
Dog/cat hair: Very short staple. Blend 30–50% with wool for easier spinning. Use supported spindle for pure pet fiber.
Building a Spinning Practice
A beginning spinner should expect:
- Week 1–2: Uneven, over-twisted, breaking yarn. Normal. Keep spinning.
- Month 1: Recognizable yarn, still lumpy in places.
- Month 3: Consistent enough for weft yarn in simple weaving.
- Month 6: Warp-quality yarn possible with attention.
- Year 1–2: Fine, consistent yarn across a range of fibers.
Speed comes after consistency. A community rebuilding textile capacity should prioritize training 3–5 dedicated spinners and pair them with equal numbers of fiber preparers. A full-time spinner can produce roughly 100–200 g of worsted-weight yarn per day on a wheel, depending on fiber type and yarn fineness.
Yarn is the foundation of everything woven, knitted, or sewn from fabric. Every other textile skill depends on a reliable supply of good yarn. Invest in spinning early, teach it broadly, and the community gains durable clothing, warmth, and trade goods that compound in value over generations.
