I’m a huge fan of this yarn: Koigu Kersti Crepe Merino. It is 100% wool, but is so soft and NOT itchy! I’ve made mittens out of these, but decided to frog them in favor of learning to knit a little sweater. So after frogging the mittens, the yarn is super kinky and compressed. I wondered what would happen if I wet it and let it air dry… I was amazed! It poofed out and ironed itself out. I’m now going to spread the ball out in hanks and wet it and let it hang to air dry before I knit my first sweater.
