My experience is that when you are going to machine quilt, or hand quilt, if you are birthing a quilt, you have to make sure that the top, bottom, and batting are perfectly aligned and sandwiched. If the bottom is bigger than top, you will be disppointed with the puckers that might happen. I have made about 1000 quillows in my life and birthed every one, tried machine quilting, but ended up being satisfied with tying the quillow. My suggestion is to sew around edges using a walking foot.
