Adjust tension on drop in bobbin
When I was sewing the other day my fabric sucked down in to the bobbin and made a mess. I tugged, pulled back and forth, but finally unscrewed the plate and saw there were threads wrapped around a little finger like part that I had to cut out. I cleaned it out and screwed the plate back on. Now my tension is screwed up. The top thread just lays across the fabric no matter what number I put on that tension dial. I suspect I loosened the bobbin tension when tugging, but I have no idea how to tighten it on a drop in bobbin. Has anyone ever had this problem?
