I have been more or less moping the whole day. There's about a hundred and one other things I could and should have been doing but instead I have scouring the internet for causes of migraine. I'm feeling all kinds of grumpy today - found out that one of my balls of wool is a different shade from the rest. Two balls actually but one has already been knitted in. The perfectionist in me is screaming to tear it out. Seven inches of stitches. I battled with myself the whole night and finally persuaded me to stay with it. Then could I have purposely made a mistake that I cannot undo (??) so now I'm stuck with loops of undone knits that I shall consult the guru tomorrow and if she has extra wool, then I really shall take that offending ball out nevermind if it costs me three days of work.
