My new kitchen has 2 sets of molding for the wall cabinets...a 7"
vertical board to cover most of the space between the top of the cab
and the ceiling, and crown molding on top of that. One wall is about
12' long and the molding comes in 8' lengths. Since its stained
cherry with different grain patterns and variation in color, a visible
seam is inevitable.

I've already installed the vertical boards and decided to put the
miter joint in the center of the wall..so I have 2 6' pieces. The
seam is NOT lined up with a cab door or frame line. The question is
where to put the crowm molding. If I put it in the same way, I'll
have an obviously long vertical line. Should I put the 8' crown in
the middle of the wall and then 2 2' sections on either end? I'll
have 2 joints but that will break up the vertical lines.

What do pros usually do with long walls??

Thanks!
