Phone cases are a dime a dozen, but swapping them out frequently can become expensive. A great way to give your phone case a new look is by covering it with washi tape, or translucent decorative tape. Washi tape comes in so many colors and patterns that you can make a customized phone case in a matter of minutes and with very few other supplies. Just choose a new or used plain phone case (clear or colored) and washi tape in as many different colors and patterns as you like, and have a small manicure scissors or craft knife on hand. The options are limitless.
