Hi everyone. I am new to this forum and new to knitting. I learned from my grandma when I was young and then just about a year and a half ago started knitting again. I really enjoy it. And I really love this site. It has been so helpful. My question is I just bought a nice clean bag of miscellaneous yarn at Goodwill. None of it had any labels so I can't tell what the fiber is. My question is, how can you tell what kind of fiber it is? It feels like wool and cotton but I'm not sure. :thinking: Any help would be great. Thanks.
