I ran across that video several months ago, and since then I have been setting my tension following that method for all of my sewing. I like the stitches that I get with the looser bobbin tension where the thread glides out of the bobbin, rather than having enough tension to pick up the bobbin. I think my tension is OK.
My fabric is probably too tight, in the frame.
I like the the idea of changing one thing at a time. I'm going to:
1) switch size 14 needle, large eye (I don't have any 16, but I'll get some)
2) loosen fabric on takeup bar
3) adjust the distance between the fabric and the bed of the machine
4) thicker thread (Aurifil 40)
5) change to a softer top/bottom fabric to match the fabric used for the quilt
6) size 16 needle once I get some
7) play with the thread tension
I'll post the results. Any guesses as to which step will get out of my current predicament?
