Thanks for sharing the information. It would never have occurred to me that I might need to take a pressing workshop! I learn something new every day on this board! I've probably seen vintage clappers in antique stores and had no idea what they were. It looks like something I need right now! How did this simple tool ever fade from common use? I've also never heard of a Steady Betty, which looks like another must-have. I have had a tailor's ham and seam roll forever.
