I recently finished finishing my basement if that makes sense. It was partially done when I bought the house with a drop ceiling in place. In one spot on the ceiling there is a sealed off heat vent that makes it impossible to put a tile in that spot. I'm just wondering want I can put up there to hide the hole and make it look clean. Its about a 16 1/2 by 12 (inches) rectangle that needs to be covered. Any ideas? I want to get this DONE. Thanks in advance.
