Artwork. It's a fundamental layer in your home and adds texture, color, and meaning. It can be traditional art — a painting, photograph, print, or a poster — made by you, a friend, an artist, or even your kids. It can come from a gallery, a thrift store, or from Etsy. Or it can be common household items, like dishes or scarves. One thing it doesn't have to be is expensive. Check out these ideas and projects, then create your own interesting, unique ways to add a finishing touch to your walls.
