Fall is finally here which means it’s the prefect time to start weaving with (and wearing!) wool. The most common type of wool in the US is sheep's wool. In her article, Fiber Types: 101—The Basics from the Fall 2025 issue, Amy Tyler goes into more detail about wool, where it comes from, and why it’s such a beloved fiber. Below is an excerpt from that article and, as an All Access Subscriber Exclusive, three of our favorite wool projects to get you started on your autumn weaving.
Most sheep wools share some common characteristics: they are warm, elastic, and durable. Wools can absorb a significant amount of water and still be warm; they are strong when dry and much weaker when very wet. Wools usually require handwashing to prevent fulling, although the amount they shrink varies across breeds.
Other characteristics of wool also vary considerably across breeds. Some produce very soft fiber (Merino or Cormo), while others produce exceptionally strong and durable fiber (Suffolk or Montadale). Fabrics made from breeds such as Targhee are wrinkle resistant, while those made from Merino are not. Some grow their fleeces at a rate of only a couple inches per year (Suffolk), but others can grow up to 12 inches in the same period (Teeswater).
One of the special characteristics of sheep's wool is it's ability to full and felt. For her Snow Mittens in the Winter 2023 issue, designer Brittany Wells gently fulled her wool fabric. Doing so allowed her to cut out the pieces for her mittens without the yarns ravelling. All Access Subscribers can download the project below! Photo by Matt Graves
The process for taking wool from sheep to yarn includes several steps. The fleece is sheared from the sheep (a step that provides wool but is also important to the sheep’s health and well-being); that fleece is skirted, or trimmed, to remove all seriously dirty bits. Then it’s washed (or scoured) to remove dirt and lanolin, before being prepared for spinning by some combination of teasing, carding, and/ or combing. At this point, the fiber is ready to spin into yarn.
Some wool is prepared and spun into worsted yarns, which are smooth, dense, and durable and have a good amount of twist. Other wool is prepared and spun into woolen yarns, which are fluffy and provide high insulation; woolen-spun yarns are more likely to pill than their worsted counterparts. Superwash wool has been mechanically or chemically altered to prevent fulling or shrinking, even when it is machine washed.
So there you have it! While there is so much more to wool and what you can do with it, Amy's article is a great primer—make sure to check out the full article in the Fall 2024 issue so you can learn about other animal fibers as well.
