People doing contemporary homes should consider mitered edges rather than waterfalls, bullnoses, and ogees.  A miter is an edge that is cut on the diagonal and seamed through the corner.  It hides the seam extremely well and enables us to make the edge any length you want.  Here is a photo of an island countertop we installed near Houston, TX.  The material is Caesarstone Nougat.  It is modern way to get end panels on an island.
