I have used skeins of Paton wool for years. This past week after finishing one mitten and starting a small scarf, I switched to another identical skein. I was horrified as after the first twelve rows, the yarn would break apart about every three feet. Looking at the remaining yarn, I can see the very "thin" stretches of yarn. If I had only kept the sales slip! Has anyone else experienced this with Paton yarns of late? What other brand would be recommended?
