OK. So these clients had an antique dental chair that needed re-covering. Vinyl? Leather? Something wipe-clean to sponge the blood off? Well, they chose raised polka dots. The customer IS ALWAYS RIGHT. You know what? They WERE right. Properly potty, or should that be dotty? It’s one of the things I like upholstery- how switcheroo-ing a fabric can slap a piece of furniture back into life.
