Aligning Wood Grain

Just a pet peeve of mine, even though this will be (mostly) covered with a coat of paint, I need to have the underlying wood grain aligned the way real life wood structures would be built.  Wood grain tends to run parallel to the longer surface because trees are tall and there's more length to be had in that direction.  Some high end wood products may have more seamless wood grain, but this is meant to be a humble, comfy kitchen.

Three grain directions:  Horizontal front to back, Horizontal side to side, and Vertical.
