UNITED STATES,..Florida,..i need roughly 10 sq ft of Nero Marinace Granite (http://tanbrown.org) for a vanity Counter (http://GialloFiorito.com) top that'll have a chisled edge on 2 sides. I know the chiseling part will be up to my fabricator, but i'm not sure if i should figure in more inches for that kind of edge as opposed to, say, a stand (http://maplered.com) ard bullnose. Help?
