Thanks for all of the tips everyone. I'm usually using 100% cotton batting and most of the time I have a walking foot attached, but not always. I spray baste, but perhaps I should hand baste as well. I don't starch, but I do seriously iron. I work from the center of the quilt out, sometimes doing a square at a time and other times sewing an entire seam to the end. Many times, my quilting turns out fine, but it's always a struggle to get it right. Anyway, I thought I'd bring up this topic, because I'm sure that I'm not alone.
