This picture sums up my weekend knitting perfectly. I would knit a few rows, decide I didn't like the pattern I was knitting and rip it out. I'd start again and find that I messed up the pattern. So I'd rip it back, pick up the sts and carry on. I repeated the messing up part 2 times while watching the Super Bowl. Apparently watching my team loose badly affects my ability to work a simple k2, p2 pattern!
