I can send you a case of kleenex. :mrgreen:
Sorry, that just popped into my head.
I don't have any experience with machine quilting so this probably wouldn't work but could you snip stitches on either side of the puckers for an inch or so and then restitch easing in the fabric to remove the puckers. I've done that when sewing but don't know if it would work on a quilt.
