Disguise a concrete well cover with a thin hypertufa "millstone"?
We have a 36" diameter concrete well cover right next to the house and path, and it's boring and ugly. I've racked my brain for several years to think how I can disguise it but I can't come up with anything. I've seen lots of hypertufa millstone projects, and it suddenly occurred to me that maybe I could disguise it as a millstone. Would it work to put a thin coat of hypertufa on it and carve grooves to make a faux-millstone that still allows the cover to be lifted off if the well needs to be serviced? How thick of a "skim coat" of hypertufa would that require? I'd have to fake the hole in the center but perhaps an indentation would be good enough. Has anyone done this? I'd love any and all advice, I am a newbie but I'm excited about the possibility of dealing with this ugly thing in an attractive way.
