My sewing machine is making big loops on the underside of the fabric (it's the thread from the bobbin). The top stitch looks fine, but with the big loops on the back, you can pull the seam loose after you sew it. I'm sure something has come loose, but don't know what.
Any ideas what might need tightening? TIA.
