In spite of having measured these in advance, I was a little surprised at how big they were when they arrived.  I had assumed that since they are so open in the center, they would not appear as large as their measurements indicated.  Since they are quite lovely, I put them up anyway, and  although I've gotten used to them, I think they overwhelm our kitchen island.  The would be fine over a wider island, but ours, while very long, is only about 30" wide.  While each side measures about 15", the diagonal measurement is closer to 18", more than half the width of our kitchen island.  Just something to keep in mind, but if you have a wider island, these would be gorgeous.
