Kitchen backsplashes are generally plain, but adding mirrors can really make them stand out. A fun idea is to hang a mirror ball in the middle of a plate rack. The reflective surface will make it easy to see the dishes and silverware that are inside!
If you want to jazz up a bathroom, you can also use mirror balls, which can be very decorative indeed. You can find glitter balls and glitter tiles that are decorated with your favorite cartoons or movie characters, and you can also find styles that are made from the most popular plastic known as "microwaveable" tiles. These balls can be affixed directly to the wall, or you can use a special mirror ball frame that hangs on the wall behind the toilet, making it visible from any angle.
