I’m not a minimalist; for me, the effort has to have a result I enjoy and I wouldn’t enjoy the display in FGT’s photo. Otoh, if people choose not to celebrate in the same way as me, that’s also fine, be they minimalist or OTT with lights and assorted razzamataz to the gunnels.
This year we’re having a fake tree as our main tree, for the first time. I’ve ordered two different ones, so I decided which I prefer. For me, the more fake an artificial tree is, the better, so I’m probably going to choose a faux-snow encrusted one.
Although mention of kittens has now got me thinking as we have two young cats and this is their first Xmas with us.
My 6yo GD is a bit judgy about my fake tree so I might get a table top real tree in a pot, to cater to her sensibilities. 
In our previous house we had more space so we’d have a big tree in the sittingroom and a large pop-up tree in the dining room. Some years I’d have some prelit twig affair in the family room. Our fireplace was a beauty so I’d go all out with that and the mirror above it with lights, greenery, baubles, swags and bunting. I’d have a rough theme, sometimes a colour or two, florals, woodland animals, churches. . The rules aren’t absolute, though, and the old favourites come out every year, theme or no theme.
We don’t have so much space now so I’ve had to curtail the decor. We don’t have a fire any more so I now create a ‘tablescape’ as the interior designers call it, on top of the sideboard. Last year I created a village snow scene with white ceramic tea light houses, those bristle Xmas trees in different colours and miniature people. With the main lights out and tea lights lit, it looked so cosy and inviting.
I like bunting, too, so put up appropriate strings of that. Last year i managed to pull off some of the paint from the walls when taking it down so I need to be more careful this time!
