Mom & I decided to take out the microwave/vent hood, which left an unfinished wall area. The area that was finished has a really thick textured finish, which we figure would be nasty in a hurry. The thickest spots, I sanded down a little with 60 grit sanding block, then cut a thin sheet of masonite paneling & nailed it to the wall to give a smoother surface to glue the panels to. For now, I have the walls ready for the panels, but still need to glue the panels in place. In these pics, they are just held in place by the canisters.
