I am doing a wall pedestal for the first time. How do you handle the back section (cape to leather or felt backing)? Do you fold over the cape, staple it like a shoulder mount, then trim it off flush to the form when it dries? Do you staple along the outer edge and trim, do you trim flush with the form while it is wet? Seems like a silly question I know, but the transition will be a spot that everyone will be looking at, and needs to look good.
