Sometimes you have to just walk away. A friend of mine was just finishing putting the binding on her first quilt the other day...then her needle broke. Fine, change the needle...then her bobbin ran out...fine, but she didn't have any back up, so she had to wind one...fine, but then the spool of thread ran out when she was winding the bobbin - she did have an extra spool, but saw it as the third sign. She finally said after the third thing in a row went wrong that she quit. She said she had ignored the first two signs in a row that her quilt was not to be finished that night and wasn't going to ignore the third LOL
Sometimes you just have to walk away. I know I do because if I don't, I may just throw my machine out the window. LOL
