I started laughing when I read your post because all of it keeps me humble. Just when I think I have something down pat, I find out I wasn't even on the right page. I was using my walking foot a few days ago and I decided I just hate that thing because I can't get it to work right. But the last time I used it, I loved it. It's good to be humble. A friend used to say "being humble and wearing a slip are alike because if it shows, it's 'tacky'.
