I slip a microfiber cloth under my sewing machine, that sticks out the front and catches all threads. When it is so covered, that I cant clean it or run it thru the washer/dryer, I just toss it in the trash. I also often wear a kitchen apron that I roll with a lint catcher/roller tape. This helps, but I still have to sweep and vacuum. My hubby says living with a quilter is like living with a dog who sheds thread. LOL
