I have a 25 foot drywall wall left that I am doing some wainscoting... I ripped up the old baseboards, and am bumping them out 3/4" basically following this guide a bit: http://www.familyhandyman.com/walls/how-to-build-a-wainscoted-wall/view-all
So the problem is that that particular wall is a bit wavy - It was real noticeable before I ripped out the baseboards, and so I was thinking that maybe I can make the 3/4" poplar smooth it out a bit. Lining it up, I see that it can a bit, but even if it hugs the wall a little, they will be wavy to.
Wondering what the best thing to do is... sand the new boards where it's uneven, or something else?
