Masking tape has long been used for the walls, but has now changed function. It used to be used for stencils/ creating borders on the wall and covering door and window frames from paint. However now it is widely used for decorating as it can be done in any way you like and can be changed from time to time.
Washi tape comes either plain or patterned and comes in multiple tones.
Here are a few ideas to use around the home.
