I like wallpops wall decor. It is easy to apply and reusable. I live in an apartment an I don't have to have dull plain walls.
I used these in my master bath. It turned out beautiful! They went up super easy. Yet when I went to wash my mirror, 1 drop of windex got on a block and that spot turn bright white immediately. So make sure you place these a location that will not need to be clean with anything but a dry cloth.
