Spotted in the Los Angeles restaurant ink.sack: vintage frames used to highlight blackboard designs scrawled by patrons. The chalkboards are permanently glued to the wall, but the art obviously varies. For the restaurant's opening, street artist Anti decorated the walls.

To create this effect at home, paint a wall (or a section of a wall) with chalkboard paint, such as Rustoleum's Chalkboard Brush-On Paint. Then hang a selection of vintage picture frames, which you can often find for modest sums at thrift shops and flea markets; vintage-style picture frames are also available from online sources such as United Picture & Frame Co. Alternatively, use a vinyl wall decal like the Oval Frame; $29 at Dali Decals.
