LGJARN52, I first saw this idea years ago and purchased the 3" x 4'6" pool noodles years ago when I was making a patriotic quilt for my son-in-law that ended up being a VERY LARGE quilt and also purchased a dowel rod to go into the center hole of two pool noodles to make it wide enough and you are absolutely correct, it worked perfectly. I spray basted, but did not use pins at all and what a wonderful, helpful idea that was. I am glad you are sharing this idea with everyone here.
