Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
Granite Setts are incredibly hard wearing, making them a great choice for high traffic areas such as pathways like in this garden pathway design by Thorburn Landscapes. Nice design to use for narrow patio area outside french windows.
