I had problems with the seams separating when using a stitch length of 2.5 so I changed to 2.0 for regular piecing. It’s working well, although much harder to rip if I manage to sew part of the block wrong. For paper piecing I use a stitch setting of 1.6. I use pantos to quilt on my Longarm. I make sure there are curves and swirlies that will hold the Quilt together from all angles. I rarely have a spot that is a 2 inch open space although I use Warm & Natural which says you can Quilt at 10 inches.
