I believe, he is referring to the "˜fancy-wheel' employed on top of the welt. http://www.sattlerbedarf-shop.de/sho...%3DStuppr.2%26 "˜Stupp' in German, "˜Sztuper' in Polish and probably something similar in Hungarian. Yes, we use german words.. So: Fishball! This is - most probably - not a wheel. I do it with a tool, which looks a stitch marker.. A fudge wheel's (I guess this is the name), mark is a bit different. Only my opinion..
