Shetland Wool: Knitting Properties
Shetland is the traditional wool of Fair Isle and Shetland-style colourwork. Coarser than merino but with a unique sticky, slightly fuzzy character that makes it ideal for stranded knitting and steeking.

Fibre characteristics
Shetland fibres are 50–120 mm long with diameters of 23–30 microns. The natural crimp and slight stickiness of the fibres make Shetland yarn lock together when knitted — perfect for steeking, where the fibres prevent unraveling at the cut edge.
Best uses
Stranded colourwork (Fair Isle, Shetland yokes, Norwegian sweaters). Steeked cardigans. Traditional ganseys and outerwear sweaters that prioritise warmth and durability over softness.

Hand feel
Coarser than merino — not ideal for next-to-skin garments. Most commonly used for outerwear: cardigans, jumpers worn over layers, and accessories like hats and mittens.
Blocking transformation
Unblocked Shetland looks rough and the colourwork looks muddied. After a wet block, the fibres bloom and soften dramatically — the colourwork pattern jumps off the fabric and the hand becomes much softer.

Tips
- Always block Shetland aggressively — the difference before and after is dramatic.
- Shetland is the gold standard for steeking; the sticky fibres prevent unraveling.
- For sweaters worn over layers, Shetland is warmer and more durable than merino.
In depth
Shetland wool was the foundation of the Shetland and Fair Isle knitting traditions, where colourwork pieces were knit in the round and steeked open. The natural stickiness of the fibres made steeking safe even before sewing-machine reinforcement, and the fibres bloom beautifully with blocking.
