Top Stitch Problem
Can anybody help with top stitch not looking nice. I have had my machine serviced but unable to speak directly with serviceman. The top stitch is not looking like individual stitches but rather just a long running stitch. I’ve tried playing with the tension and it just becomes too loose or to tight. My machine use to do the job right but somehow it won’t now. Machine is around 5 years old. Can anybody help please. TIA.
