We have an artificial tree. I have wrapping paper and sellotape and stocking gifts all sorted plus some potential big gifts just in case that I will roll over for birthdays if we can get what they ask Santa for nearer the time. I also have bought crackers and tree chocolates. Not concerned re Turkey as any roast dinner would do. What else haven’t I thought of that I might be sad not to have if there are shortages?
(Caveat - I know of the shelves are bare then Christmas is the least important thing, and o know that we are lucky to be able to afford this in advance)
