What did you use to put the sandwich together? Spray, elmer's, etc. I used elmers with a little water to thin and found that it left hard spots. When I would do the decorative stitches, they would bunch up. I washed the quilt in the middle of the quilting process (gently in the sink) to remove the glue, and it went better after that. Not sure it was the glue, but it was better after washing. Did not think about the pressure foot adjustment.
