What is "stonish looking"? There are stone walls, and there are concrete block walls that get faced with stone. Is that what you mean? Neither one of these is cheap unless you have access to free stone and do all the labor yourself.

Where do you live?

Hey

Note sure if this is what your interested in, but these are molds for a balustrade style fence.

Hope this is of help
