I've been plagued with a question about yarn since Christmas and it's been getting bigger. Googling hasn't provided the answer.
The seed was planted when I purchased the yarn for this shawl. You'll see that I used Mountain Colors 4/8s wool. Mountain Colors' Yarn Styles page tells me that it is a "good basic worsted weight yarn."
In my google attempts, I have visited Mielke's Fiber Arts site where I found yarns referenced as 8/2, 7/4, 3/2, 5/2, 10/2 and 20/2.
And the question grows when, in those vintage patterns I've been looking at, the specified material is pearl cotton, sizes 3 or 5.
What in the world do those numbers mean? I know they must have a meaning, but I can't find a thing. Does it have something to do with the spinning of the yarn, particularly the numbers like 8/2 and 4/8? Someone help me, please!
