Thank you to Peckish (Peggi) who just last week introduced me to (my new best friend) STARCH!!!! Whoo hooo! I can't believe the difference it makes! I started with just a light spray (Faultless brand Heavy Starch- Original Fresh Scent), and that was ok, but when I really put the starch to it (pieces were literally wet), it was much better. (Yes, I screwed up and forgot to apply the starch BEFORE cutting).
But wow, what a difference in sewing! Love it, Love it, Love. IT!
Sorry; I know that my commentary didn't address the OP's question AT ALL...but I just thought I'd put in my 2¢
