Featherweight
I have a couple of featherweights that I can’t keep a good stitch on them. I clean, oil, change needles after about 15 minutes the stitch looks terrible I’ve tried adjusting top tension, I’ve tried adjusting bobbin tension nothing I’ve done will give me a consistent good stitch. I have even taken it in for service they get a good stitch but it doesn’t last once I start sewing. Please any ideas!! Carly
