I am currently trying to finish up a tank I started a couple months ago. It's knit with cotton and I find that my hands hurt after knitting on it for any length of time. Probably because the cotton doesn't have the "give" that wool does. I have made great progress, it is knit in the round until you reach the v-neck. I did add 1" of length to the body after reading the comments on Ravelry about the pattern. I had ordered 1 extra ball of yarn so adding the length was not a problem.
So now I shall put it up for the night and spin while I watch Nascar.
