I have a BB. 3/4 finished. Second year......piecing together shattered tempered glass. Tedious. Sprayed ball with copper paint first..was a terrible glow orange!
At our house..with the deer and assorted critters...sometimes the bottles are the only colors that are dependable. Had a bottle tree from a dead tree for quite a few years....but it finally decayed and fell over.
No bottles on our cedar structure...but there may be one day!!
I really don't see a space for it on the roofline.
Here are clusters of bottles similar to what that artist had on is corner posts.
And a bad shot of the bowling ball...needs cleaning.
