Bluefaced Leicester (BFL): Knitting Properties

Bluefaced Leicester (BFL) is a long-staple British wool prized for its lustre, durability, and softness. It is one of the few "next-to-skin" wools that combines softness with the long-staple structure that resists pilling.

Fibre characteristics

BFL fibres are 80–150 mm long (much longer than merino) with diameters of 24–26 microns. The longer staple resists pilling far better than merino while remaining soft enough for next-to-skin garments.

Lustre

BFL fibres are naturally lustrous, giving knitted fabric a subtle sheen that catches the light. Hand-dyed BFL takes dye exceptionally well, with rich, saturated colours.

Best uses

High-wear sweaters that need to last for years. Lace shawls (the lustre shows the lace pattern beautifully). Socks, especially when blended with nylon for additional durability.

Cost

BFL is more expensive than merino but lasts substantially longer. For a sweater you want to wear weekly for ten years, BFL is often the better value despite the higher upfront cost.

Tips

  • Choose BFL over merino for high-wear garments — the longer staple resists pilling.
  • BFL takes hand-dye exceptionally well; the colours are richer than merino.
  • Block aggressively to bring out the lustre.

In depth

Bluefaced Leicester is one of the few wools that competes with merino for softness while resisting pilling like a coarser wool. It is the workhorse fibre of the British hand-dyed wool revival of the 2000s and remains a favourite of professional knitters and serious hobbyists alike.
