I introduced a christmas journal this year and its been invaluable up to now. I have listed recipes old and new, list of people to send christmas cards to with addresses, gift lists, gifts bought, decoartion ideas, receipts and much much more. Its great and I am forever sat flicking through it.
I also have everything listed in a spreadsheet with tabs ready; gifts, cards, decorations, food, activites and other. I am loving being this much in control.
