Thanks again for your help.
Please let me add clarification about the wrinkle. The longarmer pointed out the wrinkle to me when I picked up the quilt. It looked like it could be tacked down with matching thread and be OK.
My backing was square and pressed. It had 5 inches on each side to allow for the extra fabric needed. My quilt was also square. The quilter had previously quilted a friend's quilt (same embroidery design and similar fabrics) and it looked nice.
Thank you again for your experience and help. This is truly a lesson for me in my personal quilting journey and a small glitch in the life of quilting.
