I want to make a new headboard out of old doors. How can I find that?
Headboard ideas from old doors....
Here is a headboard we made from an old door https://www.homeroad.net/2012/06/old-door-headboard.html
In the search box type in door upcycle headboard for your key words
There are quite a few such projects on hometalk, some looking like rustic doors (which would be my personal taste) and others where you could never tell the headboard was a former door! Do think about the construction of your door and if you feel you need to trim it to ensure you don't loose any pieces which hold the wood together. https://www.hometalk.com/search/posts?filter=headboard%20from%20a%20door
