I'm doing some FMQ and I'm stopping and starting a lot as I jump around outlining flowers as part of the process. I keep having trouble pulling up the bobbin thread periodically, but just enough to be a real nuisance as I keep thinking the thread is out when its not. Its a vertical bobbin and I keep wondering if one of these "genie magic bobbin washers" would help? Is that one of the things they solve in FMQ? Or maybe its my bobbin tension needing some fine tuning? Please expand on how do these washers improve your stitching. Thanks!
