Assemble the outer frame of your DIY vent cover. We glued the edges and used corner clamps to make sure the frame stayed square. We used our brad nailer to put a nail in each corner.
Once your frame is assembled, paint it. Then use metal snips to cut your decorative metal sheet to size.
Next, use you clear glue to glue the metal sheeting to the back side of your frame. Then use clamps to hold it in place while the glue cures.
