Fiber Bases

Here's where you'll find details on all the various fiber bases we use in our shop! If you see something here that we aren't currently carrying but you'd love to buy, please reach out and let us know - we're happy to dye more of anything you express an interest in.

RAMBOUILLET 

Rambouillet wool is a French cousin to the Spanish Merino, developed in the late 1700s. Its luxury fineness and incredible elasticity makes for springy, lofty yarn, and the slightly more matte surface takes colors clearly but softly. Rambouillet felts beautifully, and when spun, creates soft yarn with generous loft, and delicate garments appropriate for next-to-skin or baby use.

POLWARTH

Polwarth wool was developed from Merino sheep with an addition of Lincoln ancestry. It retains much of Merino’s softness and crimp, and gains length and drape from its longwool side. Polwarth is moderately resistant to felting and pilling, and when spun, creates yarn with next-to-skin softness, surprising loft, and enough durability for outdoor activity.

MERINO

Merino wool is a classic household name for a reason: its bright white base color, regular crimp, and fine fiber set the standard in the industry for fine wools since the Middle Ages. Merino felts beautifully, and when spun, creates soft, delicate garments appropriate for next-to-skin use.

FALKLAND

Falkland wool refers not to any specific breed, but instead to the fine, exceptionally bright white wool produced from the networked wool pool of the Falkland Islands. It can contain fibers from sheep and crosses such as Polwarth, Merino, Romney, and Corriedale. While this can create some variation in Falkland wool from various sources, it comes with the island's tightly managed sheep flocks' health, which results in fleece that is naturally disease and pest resistant. Our Falkland is comfortable next to the skin, and suitable for snuggly garments. 

FINN

Finn wool comes from an ancient breed of small, highly prolific sheep. It is medium-strong yet silky, with a gentle sheen and white with the slightest kiss of cream. Finn felts eagerly, and when spun, creates reliable, snuggly, and durable yarn appropriate for sweaters and blankets.
