Layering: Layering with a sleek mirror leaning slightly into the artwork adds perspective. A mirror is a clever way to bring the outside in when positioned correctly, or to simply open up space. In a slick condo, the layering effect offers the opportunity to bring more without adding too much clutter. Stacking: Decorating with interest-based books lets you reveal your passions passively through this subtle technique. Pay attention to size and sequence to avoid the look of piled-up books. The concept is display, not storage, but the idea does offer a clever storage solution for a book collector living in a smaller space.
