Designing With Flowers: Blocking (Or Not Blocking) The Person Across The Table

Dear Readers:

I tend to be very careful when choosing the height of my centerpieces.  Years ago, I did an amazing tall centerpiece that was blocking the view across the table resulting in my client removing them all together.  Needless to say, I was disappointed after putting in so much hard work.

That said, years of being in this business have shown me that there are two rules of thought on this. I have clients who will allow me to create a concept centerpiece that totally blocks the view of the person across the table (see the the birdcage centerpiece above for an example) maintaining that, due to the noise of the event, it’s difficult for guests to talk to those on the other side.  Then, of course, there are those who are clear they want a low centerpiece (such as the one below) so that guests can at least see one another.
Today, I would like to ask you which you prefer and why?
