it happens..? I was sewing a pocket thing that I was going to use in a prayer pillow and I took the pocket off and the bobbin thread disappeared so I went to bring up the bobbin thread and the needle won't go all the way down into the bottom where the bobbin is if the bobbin is inside the machine. I tryed taking the bobbin and bobbin holder thing out and putting it back in and it just won't work. What can I do? =(
