Wanted to add to my post that I used bamboo batting. Got it because I wanted to try hand quilting with it, but whilel pinning it,, it seemed hard to push the pins through so decided it would be hard to hand stitch. However, while machine quilting, it behaved very nicely and I do not have one wrinkle on the back and only about 3 or 4 very small places where the machine foot pushed the fabric over a seam as it crossed. very satisfied. I posted a reply on quilt as you go but don't see it here.
