We love creative groupings on tables and shelves -- and on mantles and windowsills -- even on the floor. Piles of pillows and clusters of candles make a home cozy. If the home is small, though, decorative displays can appear muddled and chaotic. Even expensive pieces can start to look like garage sale fodder if there are too many of them. To avoid giving your studio apartment a jumble sale look, provide open spaces where the eye can rest, and be selective about the objects you display. Choose one distinctive piece over a large collection of smaller pieces. If you do use groupings, make sure they share features in common, like a shape, color or texture. Vary the height of objects in a group, and keep groupings to three objects or less.
