This is the second one that I have seen an upside down tree.
When my children were young we would visit my sister's home and on the way, there was a home with two large bay windows separated by the front door.
Each of these windows displayed a beautiful Christmas tree...the only difference was one tree hung upside down.
I will have to send this thread to each of my children for their long lost memories of the "upside down" Christmas tree.
Thanks for the memories...MaryJane
