Christina, a lovely knitting designer who has a blog called "A Knitter's Life" recently posted a tutorial for making your own rolags for spinning. She purchased a group of merino wool roving samples from "Mohair and More". Christina chose to make her rolags in shades of red. After I watched Christina whip up a couple of rolags I ordered some merino in 14 Shades of Green. With a very small investment, I made enough rolags to keep me busy for days. I would guess my yarn is considered "woolen" spun since none of the fibers are going in the same direction until I twist them together. Whatever, it works and I'm having a great time spinning away!
