I left the back walls unstoned so that a could used scrapbook paper to create a fun shadow box backdrop. After applying brick and stone where u want it, paint in this order to create a faux castle stone finish. Paint a solid coat of Sandstone or Suede colored craft paint. When dry, dry brush on lightly Mudstone or Barnwood colored craft paint. When dry, very lightly and only here and there, dry brush on Antique gold craft paint.
