I feel your pain. I accidentally sewed over a safety pin that was sandwiched inside the center of my tablerunner. It too me half an hour to remove the pin w/needle nose pliers to wiggle it out.
My Babylock Symphony is only 6 months old so I was afraid I broke it. I ended up removing the throat plate (after a little oil ) then totally cleaned out all the fuzz balls inside. New needle , replace the walking foot and test stitch. Luckily both machine and tablerunner saved. You can be sure I will be checking work more carefully before I quilt again.
