Elna Funstyler, type 3003 FS. The straight stitch begins then sucks material down into the bobbin area and knots up. I've tried all the manual's suggestions and nothing seems to work
Be sure to use a brand new sharp needle that is compatible with the thread and fabric (see link below). The type of needle may need a larger scarf/groove to shield the thread (ie, top stitch or embroidery) and pierce the fabric easier.
If your machine has the option for a straight-stitch (vs zig-zag) needle plate, you may want to try using that. The small needle hole will restrict the fabric from being pushed down into the bobbin area.
