I also tried spray baste for the first time. I liked it, but I think I put too little adhesive spray because while I was quilting it, some part of the top became loose. I had to reset the glue with hot iron a few more times and put some more basting stitches to secure it, as seen in the pictures below.
All in all, I'm very happy with the way this quilt turned out.
Keep calm and fight on...................
