I have a white twiggy 'tree' that goes up in the conservatory on the 1st Dec. That's only because since the GC were little, it was [and still is] our Advent tree and was hung with tiny red stockings each with a number on and a sweet inside. The children used to take off a stocking and replace it with a red bauble. DH hangs some lights around the conservatory and I change the cushion covers to Christmassy ones, also add some Christmas ornaments to the window sills. Because it's all in the conservatory it doesn't intrude too much and we don't really do Christmas in the house until half way through Dec. For 25 years we had a gorgeous traditional tree but sadly after refurbing the house last year we realized we could no longer fit a tree in the lounge. Downsized to a prelit Scandi type twig hung with red hearts and baubles. Pretty but I do miss my trad red, green and gold extavaganza of a tree.Everything then come down on New Year's Day. Love that feeling of a fresh start on Jan 1st.
