TooCircular, it drove me nuts to. However, since I was practicing and practicing, I soon found out that I really shouldn't sweat it and let the washer fix it. In every case, regardless of the type of yarn used, it's fixed itself. Washing things, even if it's by hand in a very delicate detergent seems to solve a lot of problems we notice when we're done with a project and begin looking at it with a clearer eye.
Recently, I posted here about some yarn I had bought and said it was like knitting in molasses. It also caused allergies on my hands and it broke my heart because it was my favorite yarn. The company not only replaced that ball of yarn, but they gave me 4 more for having gotten one ball of yarn that was washed poorly. After I finished the scarf and washed it in some Woolite in the washer, I literally could not tell which end had the bad yarn, and which end was the good yarn. I'm a firm believer, now, in washing before judging.
