Sides for bookcases, cabinets, headboard...
Susie: put them together with hinges and use as a partial room divider
A headboard could be beautiful! A room divider or an outdoor privacy screen too. :)
Years ago I built a gun safe for my husband out of old long shutters that came off our church that was being renovated. Sorry, I don't even have a picture of it!
I've seen them used on either side of an interior doorway like a doorway into an office or family room from the kitchen. It looks very cool painted in an accent color of choice!
If you go to pinterest and search for recycled shutter projects you are sure to find something you can use them for.
