I love walking past the high rise apartment buildings where I live and seeing the many individual Christmas trees and different residents' lights on balconies. It's nice to see random twinkling lights 22 storeys up.
I have two boxes of Christmas tree ornaments and items I've collected over the years plus ornaments made by the DCs. I've bought some nice old glass baubles in a thrift store. They're really old.
I have a few nativity sets in different styles. The big one goes on tbe mantelpiece and we have small stockings hanging there too. We have a fabric Santa Claus filled with sand that Dcat knocks off the sideboard daily until she's finally satisfied that he doesn't bounce.
I don't buy any poinsettias because I have a cat, and also because I have a deck full of plants wintering over in all the south facing windows and there's nowhere else to put a plant.
Local Boy Scout troops sell wreaths - I've never bought one but they're nice amd lots of people do buy them. There are several blocks where the residents all put out luminaria on the sidewalk on Christmas Eve.
Some people decorate with big inflatables on the front lawn and some go to town with huge OTT displays. Local news broadcasts feature nominated displays of this sort. I drive past a few houses you would have to see to believe. They stand out not just because of the wattage but because that level of garishness is unusual. Most people put up lights on their front porches, maybe a wreath, or they put lights on a tree or two in the front yard. Some people have candle style lights in all the front windows. Then there are a good few people celebrating Hannukah, mainly with blue lights and decor, and menorahs.
Normally if people are having a holiday open house or a party their house or apartment would have more attention paid to decoration than the average home does. I'll be heading to a shindig at a friend's home about a week before Christmas and she'll have her house decorated in a very comprehensive fashion.
To each their own, right?
