Yes,  I own some Wool-ease, which is mostly acrylic. I don’t really like it. I bought it when I was new to knitting. It will be okay for some projects, but I really prefer natural fiber, and my real preference is naturally dyed or naturally colored fiber.

So I have some yarn that I balled with my ball winder and now I’ve forgotten if it is all wool or not. I found on the web you can test a scrap by putting some of the yarn in a cup with some undiluted bleach overnight and if it is all wool there will be pretty much nothing solid left.

BUT – brain on – a much faster test is to take a two feet of it if its worsted, or an equivalent amount in other weights, and try to felt it by rubbing it into a ball in a bath of hot, soapy water. If it’s a feltable fiber like wool you will know within minutes, and without chemicals, fire hazards or nasty smells. The less wool in it the less it will felt. Do a test of something you know is wool for comparison if you are not sure it’s felting as well as it should.

There is a burn test if you don’t mind your home smelling line burnt hair or plastic. Visit this link to read about it. What, no takers?
