How to Make Tree Stump Planters. (I like using tree stumps still affixed to the ground by roots after a tree is cut down, with the center scooped/carved out -- it looks a lot prettier and much more natural)
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.
