This weekend I worked on taking the air intake vent from this:
Before I rearranged the living room to accomodate the new-to-us couches and then the new television, this vent was behind one of our bookcases. Out of sight out of mind. Once it was exposed, the white vent stuck out like a sore thumb on the chocolate wall. Easy enough fix: I took the vent down, washed it, primed it, and painted it using the leftover wall paint. Now it blends into the wall much better!
