Well Schoolmarm, this is an on-going debate, but I spray baste and have for at least 120 for my 140 quilts made. When I first learned to quilt the pinning drove me mad so I tried spray basting and haven't pinned since. It took some practice but the results are so superior to pinning. No puckers at all. I really think pinning is carried over from when quilts were hand quilted because the puckers could be smoothed out in an "as-you-go" method. The advent of machine quilting calls for something different and spray basting works for me. I can spray baste a king quilt in less than an hour by myself on my king size bed, and no pins to get in the way of quilting.
