I did this exact project in my house several years ago. I went the whole route; building a frame, scoring and bending strips of rock, cutting and installing the bead.

After lots of mud, sanding, and cursing, it came out pretty darned good.

The real cursing started when a friend showed me a cataloge full of foam curves and arches that you tape in place, skin with mud and paint. That would have saved tons of time and trouble.
