I'm going to install casings around my windows. I started the other night and noticed that when I placed the vertical piece around the window, the reveal was not consistant. At the top and bottom of the vertical piece, the reveal was a nice 1/8", but in the middle, it was about 1/4".
My question is, should I install the casings so they're plumb, meaning an uneven reveal as described above, or should I try to maintain a 1/8" reveal, meaning pulling the center of the casings in after nailing the top and bottom? Thanks.
