What can I do with leftover shutters that are 8 ft. tall?

you can make it into a holiday sign, (the other side says something about Fall) hang a wreath on it, turn it into a table top or a bench seat.

I would join them with hinges and use as a room divider. It can be practical or purely decorative.

You can cut into Jackie and make square boxes for plants. You can also put together for a privacy screen.

Thank you so much for the info they all are great ways to use, will let you know witch one I do.

here are some ideas from hometalk
