Hi, everyone -- I wanted to clarify. I am an enthusiastic supporter of hearty worsted wool socks, because they're fast and they're warm. However! As long as your socks are at least 75% wool, and are knit to a fairly tight gauge so they'll wear well, any weight yarn is just fine.
I am sending out 4 packages tomorrow morning to people who asked for yarn. . . that's it for this campaign. If we get another chance to make socks, I'll do it again.
