Place a creative mailbox on the wood post, one that really shows your personality. Custom boxes come in all shapes from race cars to miniature houses. Put one up that enhances the theme of your landscaping, like a country cottage if you have a rose garden in your backyard. Standard boxes can be painted to match either the color scheme of your garden or landscape design or exterior features of your house. This idea allows you to completely customize what you want. For example, spray paint it black with moons and stars for a whimsical landscaping scheme or use stencils to add decorative elements such as fruit, like apples or grapes, if you cultivate an orchard or vineyard.
Put a wood post at a driveway entrance to hold a sign that expresses your lifestyle. Sports enthusiasts can say something like "Only Football Fans Welcome" or that fans of a certain team have to leave their gear there. For the latter, attach a decorative trashcan for visitors to put it in. Create a family wooden sign that tells who lives there. Options for decorating those include painting, carving and burning the letters into the sign. Each one gives the appearance of a different style. Other ideas include to advertise a home business, craft or hobby.
Carve the post itself to create designs or shapes. Have a custom one made into an animal shape, such as a bear or horse. Carve things into the post before painting it or staining it. Inscribe the name of your property, such as "Wind Swept Acres" and carve your family members initials, favorite quotes or simply just words of welcome. Add your family crest or other symbols that showcase what your family's passion is--whether it's fishing or religion. Put a wood at a driveway entrance that shows visitors what hospitality they can expect as a guest in your home.
