This is a photo showing how this small run of cabinets (w/fridge & ovens) butts into both walls. At one end the cabinets aren't as deep so the crown just butts into the wall and at the other end the cabinets are flush with the wall so the crown butts into it but slightly overlaps the edge of the wall. Oh, and since I'm posting from my iPad, I'm sure the photo will be upside down! This post was edited by lcskaisgir on Mon, Feb 17, 14 at 22:43

The proper way is to cut a miter for an outside corner, with the long point being the length to where you want the moulding to end (about 1/8 short of the end of the wall), then cut other piece just like you would do if turning the corner. This piece is now cut just long enough to return to the wall. It is referred to in the trade as returning a piece on itself, and is how to end all profiled material in this situation.

I would tend to do the same as S_M suggests. You can lay out the cut line with a "jigger" tool. This is harder to explain than do. You simply make a wedge-shaped piece of wood with a couple of saw-tooth cut-outs on one edge. Lay up a piece of paper and then put the point of the wedge in the critical and transition points and trace around the whole thing. Take down the paper and you can create the exact profile on the back of your molding or yet another pattern piece. I would use a coping saw, or if the piece is small enough, a band saw to trim the profile. I would tend to use a pattern maker's rasp instead of a chisel, but I could live with either. Back cutting is important. Do this profile before you cut the other end to length (assuming it's a butt or miter at the other end). You always should do the hardest part first before cutting to length. Best case scenario: you can just butt the other end into the wall and cope the adjoining piece to make an inside miter.

It appears in the drawing that you have a spacer on the right front of the cabinet. If that is so, I would move it over and finish as in number three even if you needed to get a smaller crown. If not, then I believe #2 would be the best finish.
