My spinning group is doing a breed study this year and June is my turn to present. I decided to highlight Southdown wool because I think it’s pretty fabulous. “Down” breeds come from the “downs” in England and consist of Southdown, Suffolk, Dorset Down, Hampshire, Oxford, and Shropshire. There are a host of other breeds that are considered “down-like,” but these 6 are the true downs. Southdown is the original down breed. The Suffolk, Dorset Down, Hampshire, Oxford, and Shropshire breeds were all created by breeding Southdown with other kinds of sheep to maximize different qualities.
What’s so great about Down wool? It’s springy with a diorganized crimp, the wool doesn’t have a lot of kemp (chalky, brittle fibers) or hair, and is resistant to felting (this is my favorite part). It’s also important to know that most Down breeds are raised for meat, so often their wool is inexpensive (I get mine here). Southdown wool has a micron count of 23-31 and a staple length between 1 1/2 – 4 inches. Because of the springy nature of the wool and the shorter fiber length, Southdown is best when carded and spun woolen. As with any wool, though, you can use it however you like.
I first spun commercially combed Southdown top as a new spinner over a year ago. I had a spindle and some wool and I wanted to learn everything, so away I went, spinning the wool Worsted (short forward draw). I loved how this yarn came out. The wool was so easy to spin with – just enough drag to draft nicely, but not enough to make me really work for it.
Later, I spun more of this same top when as a learning exercise (I wanted to be able to spin thick singles). The yarn ended up delightfully thick and thin.
I was curious about how resistant this wool is to felting, so I knit up a few swatches to do some very scientific research.
The first swatch was my control: I washed it with wool wash in hot water, squeezed out as much water as I could, and laid it flat to dry.
For the second swatch I let it soak in hot water for a few minutes, then shocked it with cold water. I continued shocking the swatch back and forth between hot and cold water several times and rubbed the swatch to maximize any felting that would take place. Other than a little fuzziness, this swatch looks almost exactly like the first swatch.
With my third swatch I decided to go all out. I washed and dried it with the rest of my laundry. After going through the wash, the swatch looked exactly like my second swatch: a little fuzzy, but still in great shape. It shrunk lengthwise and widened width-wise a little in the dryer. This was the most dramatic change of the 3 swatches, but I still wouldn’t say the wool felted.
I’m wearing a swatch under my shirt as I type this, and it is a tiny bit itchy. If you have sensitive skin I wouldn’t recommend Southdown as a base layer, but it would make an excellent and hard-wearing sweater or jacket. Conversely, because of the springiness of the wool, Southdown would make great socks!
Now that I’ve done a little more study on the breed, I’m taking commercially prepared top and carding it into rolags to see the difference it makes in the yarn.
Look at that loft! I can’t wait to knit this up!
