OUCH! You poor thing! I feel your pain. I also have done this. When I was a little girl, I wanted doll clothes so bad! But everyone was too busy and I wasn't allowed to touch my Oma's treadle machine. Well, the day came when I could no longer wait and sure enough that huge needle came down on my finger. Yes, I think I was hurting on both ends that day.
Hope the pain subsides soon. Sorry that had to happen to you.
