I didn't get much spinning done this past weekend, because we went out of town. However, I did spend extra time during the week spinning, as well as bringing my spindles with me to keep on spinning my wheels.
When I got back, I spent some time Navajo plying the resulting singles so I could preserve the long 8 color repeats.
While I was plying, DH looked over and asked me why I was running my yarn back through the wheel. He wanted to know if I was adding or removing twist. I told him I was plying. He said, "But there's only one bobbin."
I had to explain to him how to Navajo plied -- at least he's learning. :-)
