Well that sounds like some of the things I have done. And just this week got the thread wrapped around the bobbin case because.......i didn't unthread the needle while winding the bobbin(anyhow I think that is how it happened as I was winding the bobbin at the time) Oh what a mess that was to get undone. But got undone and I continued on and had a pretty baby quilt when done ..we all make mistakes, that is how we learn. Have fun..
