The stripe did run along the outer edge of the wallpaper strip, so I could have easily butted the edge along the door molding.
But that would have put a vertical seam running right up over the corner of the door. My experience has shown that this area gets a lot of stress, especially in the case of shifting foundations and walls. So I really avoid letting a seam fall there.

We had very little paper for this job, so before cutting anything I made sure that reducing the width of this strip by one section of diagonal motifs would still allow me to reach the corner on the far right (not shown).
So I measured down a little more than the height of wall above the the door and kept that intact and full-width. The rest of the length of that strip I cut along the strip in the design, all the way down to the floor.
Here that strip is in place. Leaving the top portion a little long ensured that I had enough to cover this area, and then all I did was trim off the extra 1″ or so, just as you normally would trim around a door frame.
The best part is that we now have the paper reaching across that “danger zone” above the top right corner of the door, with no seam to split open or gap should the wall shift.


Note that this is a very easy pattern to play tricks with, because, although there is a pattern match, it really doesn’t matter much if you ignore it. Also, the lines are not perfectly straight, but a bit squiggly, and that makes it much more forgiving.
In fact, because we were really short on paper, the only way to get the room done was to mis-match the design in most places. The homeowner was OK with that. In fact, she (and he) were delighted with how the room turned out.
