A friend was using a strand of Chroma along with some alpaca to knit some great looking socks so I ordered some from Knitpicks.
I guess I was thinking sock yarn, since it is 70% wool/ 30% nylon so was surprised to see that it was a singles yarn. Then it isn't superwash, either so I wasn't about to make socks out of it after all.
Much preferring plied yarn, I added more twist to the fingering yarn I had purchased and then plied two strands together and we were off!
The patterns are a syntheses of Charlene Church's Hat's On! with some ideas from Anna Zilboorg.
