An RV remodel is not for the faint of heart sewers, but is very do-able with a little know how and a lot of patience. You can use the fabric from the old cushions as a pattern and even reuse the zippers if they are still in good condition. For sewing on the buttons, use a 4" to 6" long needle and heavy duty nylon thread. If your thread is heavy duty enough, you only have to go through the cushion once to get to the back side, catch the back button, and then through the cushion again to the front to catch the front button. leave enough of the knotted end on the front side so you can tie off tight with the remainder thread. This old RV went from yuck to very hip, functional, and stylish. Way to go Angie!!!
