Thread Bubble?
Another basic question that I probably would have learned had I took Home-Ec in high school LOL - This one is related to thread/stitching.
The best way I can explain it is like the machine is stitching just fine, but somehow there is also another string that somehow covers 5-6 stitches and just kind of hangs on top of the other stitches.
Is this potentially just a tension thing that I need to adjust - or something that I'm doing?
