some of the yarns do have a label that tells you where to pull from but it never minimized the yarn vomit for me. :shrug:
I think there is SUPPOSED to be a way of looking at the label and determining the correct side. If my memory serves it is when you are looking at the label in your hands the correct side to pull from is the one on the right.
but I am left handed and often backwards when it comes to things like that...lol
