Be sure to press SA of turning space back, too.(placing an old envelope to act as a guile keeps th section straight) Then when you turn it inside out, you are working with on pressed seam that will lay flat and when sewing turningspace you will have a straight fold to work with.
I must add that I only use flannel or a Good weight cotton as batting in TRs and treat that as part of the backing fabric.
Well, Bob, I had to read through this several times to really figure out what you are doing here, but I finally got it. You gave good instructions. It's always easier to get turned seam to look flat and neat if they've been pressed open before turning. That way both pieces of fabric have already been pressed in the right direction.
