Drywall – Ideas for 1″ of ceiling/crown trim

drywalltrimwindows

I'm drywalling around a window. The window has a 12" deep "frame", which I plan to drywall on the sides and the top, and then make a wooden sill on the bottom. The problem is that the top of the frame's framing is about .5" below the room's finished ceiling. When the "ceiling" of the window frame gets drywalled, it will be about 1" below the room's ceiling.

The question is – how do I make this 1" "drop" look good? I could just cut a really narrow piece of drywall, but I feel like having a 1" 90 degree "step" at the top of the window will look kind of tacky. I've thought about adding a bull nose bead, but it might be a really snug fit and tough to attach the top side of it. I've also looked at various molding at my hardware store, but none of it is as narrow as 1" – most of it starts at around 2-2.5" wide.

Any ideas?

Cut out the plate at the wall. let the drywall run up to the window and add a minor piece of wood, something like lattice to cover the difference at the edge of the window to the new ceiling extension. It may take 2 pieces to form a new corner at the window, but I think the corner would be better at the window rather than at the wall face.
