Per Richard Hamilton's suggestion, I re-hung the botanicals over the sofa.  I used an old Martha Stewart trick that works like a charm.  Cut templates for the pieces, place them on the wall, nail right through the paper once you determine where it should go.

Works like a charm.  If you use newspaper, as I did, do make sure the bothersome "enhancement" ad is to the wall to avoid awkward questions from any loitering children.

Why, oh why, did I not buy six of these when I had the chance?

p.s.  Joni suggested this a while ago, but I was too lazy to measure it out.  A dinner party this weekend spurred action as they always tend to do.
