Most often, when you look in a home decor magazine you will see throw blankets draped over a chair perhaps as an accent. You have to admit the eye is automatically drawn to it.
Sometimes when we try this in our homes it just doesn't seem to work or give the same effect. This is most often because it's not the right design for the room, the colors are clashing with the room itself or it's just not being displayed properly. Make sure that when using throws for decoration you pick the throw that will match you decor and that it is displayed in a proper manner.
