Because the GOTS classes all shorn animal fibres as “wool” (which is also consistent with Canadian Government Textile Labelling Standards), we have to call it wool, but it’s actually 50% Wool, 25% Alpaca and 25% Cellulosic Viscose (Lyocell.) A little-known fact is that many viscose fibres are toxic to the environment – the viscose in Eco Tweed DK is very different! Using the Lyocell process, this viscose is completely benign and free of any toxic chemicals! Because this yarn is woolen spun, more air is trapped alongside the fibres, giving it a larger number of meters per skein. Woolen spun yarns are loftier, more elastic and lighter in weight, making for a luxuriously soft knit!
