I'm so excited to be using these wonderful air grilles on a project now. From Patterncut, they come in a multitude of sizes and patterns. You can get them in oak, maple, or cherry, sanded ready to paint or stain, complete with screws. The patterns are laser cut and start at $30 a grille. They have louvers in a separate plate behind the grille, so you can adjust the direction of your air flow.
Viola!
