Trimming interior window when a beveled cedar piece is present
Ok — I tried to follow “best practice” (I hate that term, but fine!) in installing a bunch of new windows into new construction. One of these steps involved the (new to me) process of laying a piece of beveled cedar on the bottom of the rough opening. Theory being that water that somehow makes it inside will drain to outside. The cedar (a piece of finger jointed lap siding) is resting on top of the Dow FlexWrap flashing, so in theory this should work.
The question I have is: how the hell do I make this thing look decent now? Instead of a nice flat rough opening upon which I would have installed some primed FJ wood, I now have this goofy tilted piece of cedar sticking in there. Maybe I misunderstood some part of this? Am I meant to cut the cedar flush to the inside face of the vinyl window?
Do I have to monkey around with a bunch of shims in the opposite direction in order to give me a level surface on which put my trim?

The easiest way for new construction is to cut your cripples at 5 degrees to provide the slope that also gives a level and slightly beveled window frame. For retrofit, (in a residing job) I cut a 3/8" thick board with a bevel on the last 2 1/2 inches that is flush with the inside framing (for 2x4 wall with 1" of r-sheathing plus drywall, that's 5" wide). I then flash all of it with zip stretch tape. then the window stool easily fits. I also level and screw a couple of shims to the framing for the window to sit on so I have a 1/4" between window and framing to foam.
