Woollen vs worsted spinning: what's the difference?
Almost every hand-spun yarn leans toward one of two families: woollen or worsted. The difference isn't the breed of sheep. It's how the fibres are prepared and how the twist enters the drafting zone. Get that distinction and a lot of spinning suddenly makes sense.
It's about air, not wool
Despite the name, "woollen" and "worsted" don't refer to a type of wool. They describe two opposite approaches to building a yarn. A worsted yarn is smooth, dense, and strong, with the fibres lying parallel and the air pressed out. A woollen yarn is light, lofty, and warm, with the fibres jumbled and air trapped throughout. Most real-world hand-spun sits somewhere on the spectrum between the two, often called semi-worsted or semi-woollen.
The two things that decide it
1. Fibre preparation
Worsted-style yarns start from combed fibre (top or combed sliver), where the fibres are aligned and the short bits removed, so everything runs parallel. Woollen-style yarns start from carded fibre (rolags or a batt), where the fibres criss-cross in every direction, holding air between them.
2. The draft
In a true worsted draft, you keep twist out of the drafting zone, smoothing the fibres forward against the incoming twist so the yarn stays compact. In a woollen draft (the classic long draw), you let twist into the drafting zone and pull the fibre back against it, letting the yarn puff up as it forms.
How the finished yarns compare
| Worsted | Woollen | |
|---|---|---|
| Prep | Combed (top) | Carded (rolag, batt) |
| Draft | Twist kept out of the zone | Twist allowed into the zone (long draw) |
| Feel | Smooth, dense, sleek | Lofty, soft, airy |
| Warmth | Less (fewer air pockets) | More (traps warm air) |
| Strength & drape | Strong, with good drape and stitch definition | Softer, fuzzier, more elastic |
| Good for | Socks, lace, hard-wearing garments | Warm jumpers, hats, blankets |
Which should you spin?
Choose worsted when you want durability and definition: sock yarn, cables, crisp lace. Choose woollen when you want warmth and softness with less fibre: a cosy hat, a lightweight jumper, anything you want to bloom in the wash. Many spinners settle into a semi-worsted draft for everyday yarn because it's forgiving and quick while still giving a smooth result.
The best way to feel the difference is to spin the same fibre both ways and compare the skeins: their WPI, their grist, and how they behave when you wash them.
