When you’re ready to order, you provide your actual post-to-post measurements. Sections are built only about one inch longer than your actual measurements, so accuracy is important. Typical lumber is cedar 2×4 which works well for projects where posts are 6×6 and larger. For 4×4 posts, 1×4 lumber is recommended. The mountain laurel branches are woven between the boards. Pattern is random with the exception of the sunburst.
