Shameless Product Endorsement:
Any knitters out there?
You have got to try Dream in Color.
Superwash wool, toss it in the washer, toss it in the dryer. Warm, comfy, mostly non-itchy.
I've only used Classy (worsed weight), but there's also Smooshy (sock weight) and Groovy (chunky weight).
Try it, you'll like it. The colors are to dye for. Ba-dum-dum.
