Peruvian Marching Power

My first attempt to know something entirely with the yarn in my left hand. This one is called Marching Alpacas Hat. That left-handed experiment ended when I discovered holding a color in each hand was easier. The brim got naffed up because I didn't know how to purl continental style. You still have to wrap the yarn, apparently. It wasn't the best combo of yarn and needles. Lamb's Pride worsted on a size 7 needle not great. I will persevere.

The temperature blanket is growing slowly, and I'm on the last bit of the mara shawl. My fingers have been hurting a little, and I'm not sure why. Is if from yoga, too much knitting, arthritis, or what?
