I wanted to read about the gripes of other quilters. The bobbin running out and not realizing it until I've gone through so many pieces. I've heard some machines have a bobbin minder that lets you know when the bobbin thread is low. Any quilters out there that have that option and does it work well for you? Secondly, I don't know if I could call this a gripe but I don't care for sandwiching the quilt. I must 7 or 8 tops to do, mostly charity.
