Are you ready for more sheep facts? Our two previous posts discussed Merino sheep and fiber: the history of the breed, where they’re raised, and the characteristics of the fiber. In our last post about Merinos, we’ll discuss the fiber as used in yarn and textiles.

Fact #1

Within the Merino family, the fiber shows a surprising range of fineness, from ultrafine (below 12 microns) to strong (as much as 26 microns; see Note 1). Although all Merino fiber is generally considered fine when compared with other fibers, and it is considered soft enough to be worn next to the skin, there are variations in properties that are important to consider when selecting Merino for a project. If you’re looking to make a garment or accessory that will be worn without another layer, such as a delicate sweater or shawl, look for a fine (or even extrafine or ultrafine) fiber for maximum comfort and coziness. For more utilitarian pieces such as everyday scarves, a medium or strong Merino fiber would be appropriate.

Fact #2

Merino fiber is predominantly white—but not exclusively! As one of the most intensively improved sheep breeds, Merino fleece has been bred for consistently white wool. It’s one of the things that makes this fiber so versatile: most of it is literally a blank canvas, so dyers can really play and experiment with color. You might be surprised to learn, though, that some shepherds work to develop color genetics within their Merino and Merino-family flocks, producing a range of lovely natural hues.

Fact #3

Merino wool felts easily, so you should avoid agitation when cleaning or handling Merino fibers, yarns, and fabrics unless you're working with superwash wool. Until recently, it was difficult to find superwash wool that wasn't Merino, but you may spot superwash top made from Targhee, Bluefaced Leicester, Corriedale, and other wools.
