Help on 1957 singer
I inherited this machine from my mother in law and though she's a great machine I'm back,g problems and maybe you can help. I was given three box's of upholstery samples and want to make some pillows and bags with them. I'm using a 16 -18 needles, upholstery thread and a 40wt in bobbin. It starts to sew fine, but then it misses the stich or it gets tangled. Any suggestions, or is this machine not able to handle large bulk.
