I had that with my last quilt I worked on. I cut out a piece of notebook paper to fit inside the bobbin case before I put in my bobbin. That worked for me. I think they sell something like this but I don't know what it is called and I usually do my quilting on Sunday. No shops open withing an hour or two drive and I don't go that far for supplies if I can help it. Paper worked for me. Good luck.
