When I put the blog up of the bottles on the pole, one of my customers commented that it was a bottle tree and they have one near them.  Well that was the first I heard of them but much to my surprise the other day I saw them for sale in the yard of a gift store in Mercer!  And they had lots of them! The trees ran $65 – $125 without the bottles although the bottles were all around $2. She had some really beautiful and unusual ones.
