I am installing new countertops (ready made formica from big box) and the longest piece is along a wall with a bow along its length (ends stick out about 1/2") . My question is: what is the preferred method of making the backsplash meet the wall? 1) Cut the top of the backsplash to match the curvature of the wall or 2) Cut into the drywall so the backsplash goes into it or 3) Open to ideas. Thanks, Dave
