What procedure should be used to install a flagstone patio?

• A. Start at the edges and work toward the middle
• B. Start in the middle and work toward the edges
• C. Start at the high point and work toward the low area
• D. Start at one end and work toward the other end

Answer: (A)

Starting with the outer border and working inward establishes a stable reference line for the whole patio. Laying edge stones first creates a defined, straight frame that you can rely on to keep the final shape square and the gaps and joints consistent as you fill toward the center. Once the border is in place, interior stones can be fitted against that frame, making cuts where needed to maintain a neat, even pattern. Beginning in the middle or moving from a high point to a low area doesn’t give you that solid edge reference, which can lead to uneven outer edges or misaligned joints. So starting at the edges and working toward the middle provides the most reliable, visually clean result.
