Idea 1: Forms
We built forms out of melamine and used scraps of foam insulation that we irregularly sanded on one side to create the raw stone looking edge on the finished tabletop. Our finished tabletop size for this particular space was 22"x16". The install required that we be able to secure table into a wall stud, so that factor was taken into consideration with the design specs. If you will be setting yours atop a traditional base/four standard legs instead of two angled wall supports, you need not worry about that.
