I have a set of pressing bars that are strips of nylon that were designed for making flower stems and such for applique and stained glass quilts. The card they came on says "W.H. Collins Co, Whippany, NJ" I bought them in a quilt store at least a dozen years ago - maybe 15 or more years ago, now that I think of it. The idea has been floating around a long time, and I don't think anyone can accuse anyone else of infringing. It's sort of obvious as you iron things with a ruler nearby that there are times it would be great to be able to fold right over that shape and iron a crease.
