I need some help building a well. This isn't actually for Halloween, but I thought I could get some input here.

I'm building a well. It will be about 4 feet across and just under 3 feet high. It isn't like a wishing well with a bucket or roof. It's a stone circular well, possibly with a small 'ledge' of stone on top so that you could sit on it.

It's actually a prop for my church. It's for the story of the woman at the well.

I have a design that I want to use involving plywood cut into a circle 4 feet wide, with a 2 foot circle cut out of the middle. So basically a donut... two of those. Then 30 inch 1x2's (or something similar) that attach to the bottom donut. The top donut will rest on the 1x2's that go around the circumference. It'll end up looking like a circular cage. That's the foundation.

My problem lies in what I'm going to use to make the well look like stone. I want it to look like stacked rectangle stones - very old, not chiseled from a machine - very rough... think 2000 years ago made by a poor village - not something made by Rome.

My first idea was to make the foundation like I explained, then wrap it in visqueen (heavy plastic), then with wire mesh. From there I'm stuck on what material to use to make it look like stone. I don't think foam will wrap around a circle that small without breaking. What about monster mud? Is that a possibility to mold/carve into rectangle stone? I've never worked with it.

Any ideas? Stone walls on flat surfaces are no problem, but this round wall is getting me stuck. Weight becomes an issue as well, so keep that in mind.

Thanks for the help.

This picture resembles, roughly, what i'm looking for - except mine will be much much smaller!
