Building Blocks for a Perfect Patio

The oldest paving material, natural stone gives a patio timeless appeal. Pieces that are cut into uniform shapes look tidy and crisp, while jagged, irregular edges result in a casual look. Dense stone, such as bluestone and granite, resists flaking in freezing weather and isn't likely to sprout a crop of slippery moss. But softer, more porous limestones and sandstones are fine choices in warm, dry climates.
