I'm glad I found this thread! I was wondering, though, if you piece your batting, does it affect the quilting you need to do to make sure it stays in place, or is the zigzag strong enough to hold it all together no matter how densely you quilt? I have really only done stitch in the ditch quilting so would probably try to make sure the zigzag seam is slightly offset from the quilting lines, but the idea of the serpentine join that FoxyLady suggested might be an even better idea to keep it from having one easy separation zone... Any thoughts on this? I'm still on a pretty steep learning curve and would be grateful to hear more from you experts out there!
