I'm cheap. Really cheap. And I had a thought that I have a couple of old heavy wool Army blankets.
What about folding them into the proper thickness and maybe even placing a damp cloth between the folds while you are pressing?
Yes? No? Don't be so gosh darn cheap, Watson?
(Remember, I'm not only a quilter, I'm a horse owner and they need the blacksmith every 6 weeks for a pedicure! Gotta save my pennies.)
