Speaking of starch....I once (many years ago!) marked an entire wholecloth baby quilt with a regular graphite pencil before I quilted it. :shock:
As luck would have it, I had heavily starched the fabric before I marked it, then got scared because an experienced quilter said that I would never get the marks out.
I went ahead and quilted it, and when I washed it, all of the marks were GONE!! I now know that the starch forms sort of a shield between the fabric and the pencil marks and the marks just wash away with the starch! If you do something like this, always pre-test your technique before you commit to the whole project!
Nancy, be sure to look for WASHABLE markers!! I use them all the time and luv 'em!
