Thanks so much everybody for your thoughts.
I was so impressed with how soft it was at the store and paid $8.95 per skein. Later I saw that it was cheaper online, but then with the shipping.... maybe it all evens out in the end. Anyway, I'll definitely do socks with them. It's great making two of them at a time on two circs 'cause they're completed at the same time.... no more orphan socks laying around! Yay!
