Hetty, that 'wear' along the bottom edge is what I was referring to when I said they recommend the cut edges be painted before installing. Any cut edge that is not painted can wick moisture causing peeling, swelling, ect. I do think it looks nice on your house there, I like the wood grain pattern too.
Cheryl, theoretically, yes mixing would be nice. But the house is only 1 story and is more long than tall, so I am afraid of making it look 'squatty' by suing two materials horizontally. I think it would have an appearance of height if we used vertical pattern and ran it from top to bottom in one solid piece. Would be nice to mix it though, and we may be forced to anyway because of the house sitting so close to the ground.
