Yes, that is what I was thinking. The batting in the seam would keep it from shifting. That's what I was confused about. All of the directions I found seemed like the batting was cut smaller and not included in the seam. I went ahead and finished sewing the quilt and I'm at the point of clipping the seams. It looks nice but I bought fabric for new quilt. This one will have flannel for the middle layer so I won't have to worry about the batting in the seam or not.
