Oh dear Muddling, I am so sorry for your loss. I didn't see if you'd made it through the season ok, but I was thinking of you and your DH.
Some people on the Christmas boards have muttered about me being very into Christmas. I am, but in a "I like to celebrate the season of peace and goodwill to all, all year round, and also be ready when the actual season comes to actually enjoy it rather than being a stresshead lost in making arrangements for everyone else" sense of loving it.
That means reviewing how last year went and deciding what to do the same and what to change early in the year.
Rolling over the gifts and budget lists - who to buy for, any ideas for each person, and starting to pick things up as I see them either perfect for that person or on seriously good offers.
Getting ahead on making things - crafts, food, alcoholic infusions etc - as they all take time and often alcohol or food items need time to mature.
And thinking about what new things I'd like to try - whether that's recipes, concerts, rented cottages (if we travel "down home") or different bird for the feast (we had pheasant one year - interesting but not for Christmas we decided).
Live365 had lovely Christmas channels all year round - that internet station has closed down but there are some available on TuneIn radio or similar - and you could always get a nice cd of choral or orchestral music, or something that you love that is Christmassy, to enjoy now and again.
I also keep 1 nice Christmas mug out all year round - which I only rarely use, mostly for Rudolph Day (25th of every month) when I try to do something Christmassy for fun and also something to plan ahead for the coming Christmas.
