The other day I had a spinning date with my friend Anna and her cousin Helena. We had a great time spinning and chatting away. Anna also brought her microscope. I had brought staples from all my current fleeces and I went bananas with the microscope. Here are some examples.
First up is the Swedish finewool, one of my favourite breeds. I think the staple is from the neck, it is very short and fine. You can see the crimp in the microscope and how fine the fiber is. There is a lot of air trapped between the winding fibers. I want to keep this air when I spin it, to make a warm and soft yarn. Therefore I spin it with long draw from hand-carded rolags.
Next up is white superfine Shetland wool, long staples of fine and crimpy fibers. In this comparison, though, the finewool looks finer than the Shetland wool, and slightly crimpier. And I can see some peat between the Shetland fibers! It is appealing to spin it with long draw to keep the air in. However, these fibers are very long and they work better with the combs to make a strong and shiny yarn with short draw. Any shorter fibers or comb leftovers will be carded and spun with long draw, though.
For comparison, here is a Leicester staple, with completely different characteristics. The fibers are long and shiny and with waves more than crimp. In the microscope you can see only straight fibers and they seem a bit coarser than the Shetland and finewool samples. It is easy to imagine these fibers organized parallel in a strong yarn. I have spun this yarn with short forward draw from hand- combed tops into a strong and shiny warp yarn.
This is so much fun!
