This large wall in a room with a 20 foot ceiling had an eyesore, a 20 ½" square vent in the middle, over the sofa.
Artaissance online offered "The Alphabet Series" by Rodney White.
We ordered the 26 pieces sized to match the vent. The "T" was adhered to the grate, and the openings cleared. All 26 pieces were then framed identically.
The "T" was placed over the exposed duct work and all pieces were spaced appropriately. The 12'h x 10'w art installation tamed the renegade wall.
By melding the art (sized from Artaissance) with the vent, we created an art installation that brought a true presence to the room and the offending vent is no longer an issue.
