Update:
I lowered the tension on my Bailey to what he suggested. Then I spent the next several hours balancing tension. I can't get mine as low as what he wants. Mine is at the lift, slight bounce stage, where before it didn't move. Tension then was at 7 (had shredding issues-imagine that). Now it's at just a tick above 2. Can just barely see the bobbin thread on top. I will be quilting 2 strata stars (table topper and tree skirt) on one long piece of backing. Good thing there's lots of room around the star points for practicing.
