I want beadboard behind the shelves in my bookcases. Like this.
I searched for wallpaper that looks like wood paneling, looked for wood with lines in it, and then this idea came to me.
I got out a scrap of basswood. Found a small crochet hook with a pointy end (I don't crochet so at least I'm using it for something!) then I scored little lines down the wood. Presto! "beadboard paneling!"
The only problem I see is making sure the lines are parallel and straight. I'll let you know if this works...
