Hello, I have been trying to sew some bike shorts on an old 60's singer and am having a hard time getting the zigzag stitches to hold...is there something I can do or is my machine too old? thanks, angela
If you have zig zag on your machine you should be able to sew spandex fabric. It sounds like the tension is a problem.
What I would suggest is getting your hands on the owners manual if you don't have one. As well, take the machine in for servicing.
It may not have been serviced in quite some time. This will cost a few dollars, but it will be well worth your time and money.
