I will look good for a while but it will fade and/or crack eventually and it will be very difficult to repair. I'd do the real thing.

stamped concrete is a horrible idea it always cracks. better to just get real flagstone.

I have no personal experience with Artistic Concrete, but they did a project in our neighborhood that looks really nice: http://www.artisticstampedconcreteofmd.com/

Does anyone have a recommendation for a company that does stamped concrete?Looking to do a combo of brick and flagstone for our walkway.
