My yarn is a superwash merino wool that I purchased at Lilies. It's handpainted by the Dyeing Arts in Omaha NE. They have a website on the ball band (thedyeingarts.com ) but it doesn't appear to be functioning at present.
The color is Limey, and it is. I just love how it turned out and the fit is fantastic.
I think I have enough left on the skein to knit a hat.
