The Knit Apothecary
Onyx - 100% Bluefaced Leicester (BFL) Wool Yarn
Choose options
Bluefaced Leicester (aka 'BFL') is a British sheep breed with long, lustrous wool. Considered a luxury fibre, this fine wool is renowned for both its softness and strength making it a favourite among fibre enthusiasts.
BFL is next-to-skin soft so it is suitable for babies and persons with sensitive skin. It has great stitch definition, resists pilling, and is exceptionally strong and durable.
Our BFL yarn is spun with 100% untreated Bluefaced Leicester wool that has not undergone superwash treatment, so the fibre retains its natural characteristics and your garments keep their shape over time.
-- OUR PROMISE --
- We only use 100% natural fibre yarn - NO SYNTHETIC FIBRES.
- We NEVER use superwash wool so your finished garments maintain an heirloom quality.
- Our yarn is always hand-dyed-to-order so each batch is distinctive to you.
- The Knit Apothecary is independent artist owned and operated.
-- ALL COLOURWAYS ARE HAND DYED-TO-ORDER --
Each skein is hand-dyed-to-order in small batches. The nature of hand-dyeing means subtle variations may occur between batches. These nuances are a part of what makes hand-dyed yarn so distinctive.
Planning a multi-skein project? We recommended ordering all the skeins you need at the same time so we can dye them together for the closest possible colour consistency.
-- SPECIAL NOTES --
- The colour saturation may differ between yarn bases depending on its fibre composition because different fibres absorb dye at different rates. For example, merino wool will absorb dyes faster and achieve deeper colour compared to silk.
- Colors may appear different on-screen versus in-person due to computer screen/monitor resolution.

NOTE: Some deeply saturated colourways may release a trace of excess dye during the first wash. This is normal and does not affect the long-term colourfastness of the yarn.

100% Non-Superwash Wool, Never Chemically Treated
Raw wool has scales; when left untreated, theses scales remain in tact so the fibre retains its natural properties and structure. This helps your finished garments hold their shape, rather than stretching or losing form over time.

Hand-Dyed in Toronto
Hand crafted in small batches, never mass produced. Each skein is like a high-quality canvas upon which we "paint" rich, vibrant colours and variegated patterns that you'll be proud to curate as part of your collection of yarn.

Frequently Asked Questions
Untreated wool has scales. When wool is exposed to moisture, heat and agitation (like during the washing process) the heat causes the scales to open up. Superwash wool is chemically processed to remove the fibre's natural scales, making it easier to wash — but often causing garments to stretch or lose structure over time.
Non-superwash wool behaves more naturally, offering:
- better elasticity
- improved shape retention
- a more traditional wool feel
This yarn can felt if exposed to moisture, heat, and agitation because the wool is in its natural state. For best results:
- hand wash in warm water with Eucalan or a pH neutral soap.
- avoid agitation and do not wring
- lay flat to dry
This yarn is smooth, consistent, and easy to work with. Makers often notice:
- it is soft enough to be worn next to the skin
- minimal snagging or splitting
- smooth tension while knitting or crocheting
- clean stitch definition
