Seriously. I'm about to throw my sewing machine out the window. It behaves... most of the time. But now and then, something causes a problem and I end up with an amazing snarl of thread UNDER the fabric. I'll go a few stitches, and when I hear/feel the "clunk" I stop and turn it over and... the entire back is a mass of thread. Where did it COME from in such a short time? I don't get it!
It's only on starts. But I notice the regular stitches aren't that even, either, so something is going on.
I found this discussion thread and I find that tinkering with the tension makes no difference. I'm not about to twiddle with a screw near the bobbin.
Looks like I'll take it into the repair shop for a tune up, maybe they can fix it. In the meantime I've got to finish some pillows and curtains!
I love this machine. It's a simple Kenmore 12 Stitch from the early 90's; my Dad bought it for me unexpectedly after the ancient blue beast I used to sit on the floor and use totally bit the dust.
None of my friends sew, so I'm out here in solo sewing land without someone to help. Drat!
