While re-starching and pressing just now, it occurred to me that I was probably not using the correct settings on my machine and that the pressure was way wrong. I was using a walking foot but didn't adjust the pressure for the high loft batting. ( When I was un-sewing I noticed that a lot of the stitching - top and bottom was ragged and uneven in many places.) I think you are right about the pressure. I'm going to do some test quilting today and see how it goes before re-quilting the baby quilt. Thanks for your comments!
