Objects work best together when they share a trait. This collection features vases in both glass and pottery, all in gourd shapes.
The same goes for this display of veined stone -- the tabletop, lamp base, and figurine -- and wood pieces, grouped into like sets. The frame on the wall shares traits of both.
Paintings and photography aren't the only things that can be hung on walls. Here freeform glass bowls are displayed in a hallway.
African headdresses above a desk make for especially intriguing displays.
Just about everything benefits from being hung in multiples. Witness these fish-eye mirrors and soft botanical prints: both would have had less impact hung solo.
The designer of this room made creative use of the molding along the top of the wainscoting: She hung a painting and collection of plates to look as if they're propped on the ledge. The height of the wainscoting makes it work.
Furnishings and wall hangings can often feel like exactly that: a group of furnishings with a group of wall hangings floating above it. To make everything cohere, this mirror and botanical prints were hung close together and low to the dresser.
Mantels and the wall space above them are classic spots for displaying cherished art and objects, but the mouth of the fireplace is often a missed opportunity. This one contains a porcelain piece that matches those on and above the mantel.
