Didn't Clean the Bobbin Case!

I had to borrow a sewing machine while mine was in the shop. Turns out the bobbin case was never taken out and cleaned under. After I was done quilting I turned the quilt over and noticed that a tons of fuzz from under the case was on the back of my quilt.

I opened up the the machine and cleaned it out. It was nasty! Can you guess where my label will be?
