Don't know if you are familiar with these

There is a radio garden program that I much enjoy through the internet, called the Gestalt Garden with Felder Rushing I think is his last name

He has as well a neat blog with lots of photos. He is where I first saw these bottle trees.

and he has lots of photos of various "trees"

I have collected some bottles but never set out to get someone to give me a hand to make one actually

Look so neat and I have just the place for one.

I like blue wine bottles best and that is not so easy to come across
