“Saw this in a bathroom in a restaurant in Louisiana. Piece of cardboard trimmed out with green duct tape and classic gray duct tape to hold ‘lid’.”
“Looks like hvac tape holding on cardboard painted green to match. Awesome!”
Next time your kids are board give them a few boxes and tell them to make a village. As you can see these Bubba kids are creative. A+
That is going to be one sad repair if it rains or snows. Cardboard is never a good choice for window repairs!
