At this point you probably know about the use of paint to create an accent wall in your place. But if you hate painting (all the taping, having to paint it back when you move out, etc.) then you should consider using wall decals instead.
Decals add a splash of color and art in an unexpected way. And they’re superior to paint because they’re actually meant to look like something (a design, a phrase, or a shape) PLUS they peel right off the wall when you move.
Decals work in just about any room, and some decals are specialized for certain rooms. There are bathroom decals, kitchen decals, kids’ room decals, etc. Check out Dali Decals for a comprehensive selection.
