Rambouillet Wool

In terms of fleece qualities, think of Rambouillet as a Merino cousin with a bit more bounce. A great wool to blend with luxury fibers, Rambouillet contributes elasticity without compromising softness. The square, dense, flat-tipped staples have a well-defined crimp that’s somewhat less organized than a Merino’s. The tips often collect dirt. Rambouillet’s high grease content means the wool must be carefully cleaned using consistently hot water (don’t let the water cool off and redeposit the dissolved grease on the fiber); its willingness to felt means you must limit agitation. Spin from flicked locks, comb, or card with fine-toothed carders or carding cloth.

Effect of Dyes

While Rambouillet wool has a more matte surface than Merino, it takes colors clearly and well.

Best Uses

With superior softness and good insulating properties, Rambouillet wool is superb for next-to-the-skin fabrics, baby garments, and other special items. It felts easily.

More Rambouillet Facts

Valued in America’s western ranges for their hardiness and ability to thrive in sparse native grasslands, Rambouillets bunch up tightly to sleep, which gives them a higher degree of protection from predators than breeds that spread out when resting.
