So I bought the yarn and salesman said it is cotton/acrylic.
I haven't bought other than craft type acrylic (the cheapest, thin kind) for a long time. I was using it for craft projects and horse bridles for my kid's toy horses and the like.
It feels slightly scratchy. I remember my grandma's "kitchen cotton" she used for something, and it feels nothing like that. My grandma's afghans she made me, one is wool, one is acrylic. This yarn feels scratchier, more like the wool.
How would I tell what fiber this is? Is it like fabric where you do a burn test? And then what?
