While I might have dismissed blackboard walls as a trend just a year ago, their unflagging popularity is making me reconsider. Home decorators continue to embrace the look, and for good reason — they offer an unexpected color contrast in a room, and are also incredibly useful. A blackboard wall in an entry is a great spot for scribbling notes for housemates or family members, while one in the kitchen is perfect for writing up your grocery list. They're also a good way to satiate scribble-happy toddlers: our kitchen blackboard wall is a great place to redirect our little guy when he's interested in crayoning over one of our other walls.
However, if you're not sold on the concept, or, if you're positive you'll tire of the look in a few short months, you don't have to paint an entire wall. Try painting a black "board" instead.
Take for instance this lovely living room. A large piece of plywood has been used to create a blackboard, which works well in the space since it acts as a piece of large-scale art as well as a practical message board in the area between the entry and the living room. Since the home is so open, this blackboard actually helps to define areas.
To try this look at home, head to your local hardware store and pick up a piece of plywood, then cover it thoroughly with several coats of blackboard paint. I personally prefer Hudson, but ask your local hardware store rep for his or her recommendations, too.
Another great idea: try using a salvaged door instead of plywood. That way, you don't have to worry about rough edges, and your chalkboard will take on an even more interesting look, depending on the level of detail in the door itself.
