Well, if I didn't smash my iPad ...I could show you!
Ok, this is a stretch...
See this bird..well imagine a colored wine bottle resting over each spike....
That is what the glass cluster looked like sitting on the top of the 4 corners of the cedar poled pergola.
....Now that I think of it..5 not three....maybe...
It was quite beautiful.. Probably used 6 inch spikes. With the sun and the glass could not see how far the spikes went up inside the glass.
