Knots? Did you say knots? If I tell you I just wound one skein into a ball ... and encountered no fewer than 70 knots, would you believe me? If you don't believe me, give me your address in a PM, and I will be delghted to mail beknotted (string of expletives deleted) thing to you!
As for it fluffing up when re-wound, that sure works! It's an unknown blend, but when I re-wound it from the too-tight cake, it came out twice the size and super soft! :-D
70 knots! i would be suing people....
