My husband and I are renting a fantastic little WWII home from my mother-in-law. The bathroom only needs minimal work. The problem is the backsplash behind the sink. There are several hand painted tiles of country flowers that are original to the home. My husband wants to keep them because this home used to be his grandmother's. The problem is that our bathroom is beach inspired. I am looking for something I can do to cover up these few tiles without damaging them and it has to be removeable. Any ideas?
