My last review I rated this yarn a 4 because it split when working with it - Customer service offered to take back what I didn't use - my reply? Absolutely not - it works up beautifully. I just need to pay more attention to what I'm doing.
My first problem came when I was winding the yarn from the swift. Several times it just pulled apart and the affected area could be 5-8 long. Then it happened several times while knitting, a weak area would show up and it would just pull apart.
