I don't know about you guys...but this is the last flush mount Friday I want to read about, so let's not make it a thing and get to the best article ever written on flush mount grilles!
Ah yes, the flush mount grille, what other way can you say "totally expensive and luxurious" without actually saying a thing and without it actually being expensive? There's no other way! Grilles attached to studs, studs get covered with mud/drywall, smooth it out and give it a paint. Voila!
