You have a lot of yarn in your stash! Maybe you don’t have the label. A simple burn test will tell you what type of fiber you have. While this is not an actual scientific experiment, you can learn quite a bit about the fiber with this test.
Watch the video to get an idea of the burning properties of man made fibers, animal fibers and plant fibers.
The only true way of telling whether a 100% wool yarn is superwash or not is to knit up a small sample and wash it in hot water to see if it felts. The burn test is the same for both of them.
So! There it IS! My unscientific experiment to help you find out what kind of yarn you have!! Now… KnitYourselfHappy!!
