Glad to help John.
The wall you are looking at is a trailer wall that moves with the frost. I am in Northern Alberta. It went to -52C March two years ago with the wind chill. I have one door that opens well in the winter and another that opens well in the summer. I didn't have much faith in trying to make a continuous chair rail, which is part of the reason that I broke up the lengths so much. It also made it easier and cheaper.
As I was writing the post, I noticed an ad at the bottom of the screen for wainscotting that showed the style I think you are describing. I associate it with New England/Shaker architecture from about 150 years or so ago. I was thinking today that it would be possible to recreate that with a veining, v-groove, or plunge type beading bit. I personally find it too "busy". I am more of a minimalist. Each to his own as the saying goes. There is no right or wrong here, all of the styles I have seen have been around for a very long time. The good part about sharing ideas is getting to pick and choose what turns you on. When you do yours send me pics. I might use some of yours somewhere else.
