I made an attempt and figured out my pinwheel looks like 2 arrows. That says what a good piecer I am... So I scrapped that. Then I got one done except for the edges and my antique zzer seems to have chewed some of it so I pitched that one. I'm also thinking the beast of a ZZ attachment isn't as nice as just having a machine you can flip a button, knob or a lever and get what you are expecting. But I did have to test the beast out. Back to the drawing board. Maybe my third attempt will be ok.
