Just an FYI:
I did try using this method on 100% poly batting. The spray starch method does not hold on the poly batting, and when you iron it, the batting flattens. I was ok with the flattened batting as it was easier to quilt on my DSM, but sure wasted a lot of time and effort in the trial and error department. lol I'd bought the poly batting for some quilts to be donated because it was cheaper, but won't buy it again.
