If the headache goes away, I'll try to knit, but it's going to be simple. I'll probably work on a sock, maybe do a heel or two but there will be no steeking, no felting, no working on the bag, or planning the sweater. If I feel better later, I'll try plain forgiving knitting.
Maybe I'll set up my dvd player, crawl back to bed and watch Mr. Bean all day. It ought to be a good day for that.
Then again, I might just crawl back to bed and think about knitting. This thinking thing is taking a lot of effort.
