OmG I have a ton of tree trimmings . Use tree trunk rounds to build a rustic garden pathway. Love this, possibly sell them in blocks measure out even for short paths and to cover the mulch under the flowers shrubs
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.
River rock in between wood and tile floors. Good idea to transition between family room with stained concrete to kitchen with slate or granite. Also possibly between kitchen/"dining area" and living room/rest of house where I want wood floors
