Re: Window trim appears crooked, but its the ceiling!
theres on of two things i would do.
first would be to level the ceiling, this would involve tearing out the existing drywall then using steel stud run the channel around hte perimeter of the room level then redrywall it trying to maintain as much head room as possible, or strap the ceiling shimming it to level then new drywall.
the other option would be to use flat stock for the trim so you wont be cutting into the profile of the trim. its still not going to hide the ceiling
fire up the saw and make some dust
