By what criteria do you decide if a machine has a good straigh stitch?
I've read on this and other forums that my X sewing machine has a beautiful straight stitch.
Another person will say that brand Y has a so-so SS and so on.
I just asked this of my wife and she really couldn't explain what it is that makes a good stitch to her.
So by what measure or criteria do you decide if a straight stitch is good or not?
