Need help with reclaimed wood wall...

Just put a reclaimed wood wall into my new office here in San Francisco. I think it looks great but in a moment of stupidity I didn't think to measure what the final gap would be at the top. I figured it'd be substantial enough that I could just cut boards to a smaller width and put them in. (Side note: should have built from the top down so the small boards would've been at the bottom) Unfortunately, the gap is super small and a bit inconsistent.So anyone have advice or ideas on how to fix this without ruining the whole thing? I really don't want to redo it but I also don't want it to look unfinished. I'm honestly tempted to try to drop the top of the wall down an inch, but I don't know if that's even possible.Pictures available here: http://ift.tt/2uMDgr7 http://ift.tt/2sIMXKs help and/or ideas are appreciated!NWKMF via /r/DIY http://ift.tt/2sP8lZO
