Delilah,
The quilt is stunning. I love spray basting too, but do mine on the wall. I am curious about basting on a bed though, especially since gravity sometimes works against me when I spread the fabric on the wall.
Do you first smooth out the backing on top of the flannel cover? Do you pin the 4 corners at all to make sure it's tight and smooth before spraying? Same with the batting layer - do you smooth it out and hold it with any pins to make sure there are no puckers?
Thanks for your help and sharing your pics!
