Katy present lists stocking list, menu plan, shopping list, budget and diary for making cake pudding etc week by week from beginning of November onwards. Keep it on the computer, add notes about what needs to be bought for next year, ie wrapping paper, bows, labels, I do not need to buy these every year as I unwrap presents slowly and carefully and re-use the paper (and the bows). Then next October when I flash it up again I am ready to run.
Prep the whole meal on Christmas Eve, including stuffing, par-cooking potatoes and parsnips and preparing sprouts. pigs in blankets (if you have them, we don't). Have a Christmas Day time table: turkey in around 8 or 9 and then no need to go into the kitchen until midday when potatoes and stuffing go in oven and so on, aiming to eat between 1.00 - 2.00. I absolutely refuse to ruin my Christmas day by being cook and bottle washer all day. An hour or so I can manage, but no more.
I am fairly low key on cleaning. How much really needs to be done? I will clean the kitchen and vaguely dust and hoover the downstairs rooms on Sunday morning. The visitors bedrooms were done yesterday and the doors shut. Including changing the bedding, it took about an hour. I will then not do any cleaning again until well into January when the decorations will be packed and away and we have been away for a week.
