Longshadow, the pin that is mentioned, shaped like a diaper pin, is much larger than a real diaper pin. It is just in the same shape. The one I have on one of my kilts is made from brass, probably 6-7" long, 1-2" wide, and weighs 4-5 oz. Plenty of weight and heft to keep down the front apron. Will post a pic if I can find one.
