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.
Rustic crates for the cake . beats the hell out of a boring ol cake table. Could make it longer or another one for gifts aswell. Would be awesome to use one of the crates hand painted w cover on it with slit for guests wedding cards.
