problem w/ double needle
I can't get the left thread to catch the bobbin thread when I try to sew w/ a double needle.
I have an inexpensive Kenmore from the 1980s. It has zigzag, automatic buttonhole stitches. Not thousands of bells and whistles, but it wasn't the very bottom of the line, just close to there.
I was successful sewing with a very narrowly spaced double needle on woven fabric, many years ago.
But I want to hem knits, and bought a few different widths of needle, and I cannot get the left thread to catch the bobbin.
The right one catches just fine--and the left threads just sort of goes up and down and up and down.
Does anyone have any ideas? I was thinking at first that it was my machine that was the problem, but lots of the tutorials say stuff like "don't worry if your machine doesn't have instructions; mine didn't, and it works fine."
I tried setting it on the zigzag setting w/ a very narrow stitch width.
I've fiddled a little bit w/ the top tensions. Haven't fiddled w/ the bobbin tension yet (though I know how to).
I'm using a "stretch" double needle, even!
