I have back and neck issues so bending over is a chore for me so I installed a logitech camera to the under side of my quilt machine so I can at least see the bobbin stitches. I also feel by hand once in a while too. Plus while I'm advancing the quilt I'll run my eyes along the section of the back that's showing on the back bar as it advances. I try to make sure there's no folds or wrinkles in my backing before I attach it to the frame.
