Grease? on quilt
While wrestling my queen double wedding ring through my machine, it somehow got hung up inside my walking foot. The bottom of the foot is open exposing the gears. My quilt now has this large blob and several much smaller blobs on it. It appears to be grease. I've never even oiled my walking foot, so I guess this was always inside it and I was just lucky not to get it on a quilt before.
Any suggestions? Other than have a bawling foot stomping fit -- that I've thought of on my own. Do I even bother to finish quilting?
