Our newest, bestest self-patterning sock yarn, Hot Socks Portofino by Grundl (93% acrylic, 7% polyester) used by Elly for these socks.  Roisin was told this was the best and highest quality acrylic and is reported to be good for socks–it’s light, springy and of course completely washable. And it is great for people that can’t wear wool. Elly made this big pair with tiny twins from one 430m ball.
