“Hanging fir trees upside down goes back to the Middle Ages, when Europeans did it to represent the Trinity. But now, Christmas trees are shaped with the tip pointing to heaven, and some think an upside-down Christmas tree is disrespectful or sacrilegious.
The trees were recently introduced to retailers for in-store displays, so more ornaments could be displayed at eye level to the buying public. And they left more floor space to hold extra stock of decorations.”
We have a shop in town that sells Christmas decorations year-round and sells cookies and yogurt. They've done the upside-down tree thing for years. Taken aback by it at first, but then I noticed how much room it made for them and just got used to it. Have not noticed it otherwise but can't believe people are copying it at home.
