Merino Wool

Although Merino wool is one of the most recognizable names in fleece, there are dozens of identified Merino breeds around the world, and the softness levels of Merino wools vary noticeably, from ultrafine to relatively sturdy. Merinos grow large quantities of dense, fine wool; the locks are blunt, often weathered, with regular crimp. The fibers’ heavy coat of grease must be washed out in very hot water with a reliable cleansing agent — and no agitation, as Merino felts easily. You can spin from the lock, comb, or card. The wool’s fineness means it forms neps easily. You may want to use fine-toothed combs, cotton carders, or fine-fiber carding cloth. To produce thick yarn, spin several thin, nicely twisted strands and ply them together.

More Merino Facts

In the twelfth century, Spanish royalty began importing rams from the Beni-Merines, members of a Berber tribe in what is now Morocco. The Spanish crossed the rams with their own ewes; the result was a fine-wool sheep like no other. It changed the world of wool profoundly.
