Reusable advent calendar for children - most days have xmas related activities/crafts/baking rather than chocolates in them. This works because my children are preschool age and I am home with them most days, appreciate that isn't case for a lot of others
Decorations made from above activities and last years being used and no new ones being bought
School xmas cards also made in above activities and no other cards given
Using up wrapping paper from last year and not buying any more - brown paper or gift bags
No xmas crackers
Opting out of work/friends secret santas as I end up giving and receiving rubbish that I don't need. Only participated in one with close friends where we set up a wishlist (don't wish for something too specific, eg asking for a mascara but not specifying brand so that part is chosen by someone else) - not as fun as don't have the guessing of who got what but at least I get something I have asked for
Kids get one thing to open on xmas day from us and that's all - mine are still toddlers and that much is more than enough. Any more is just overwhelming for them. We put focus on enjoying magic of Xmas over the month of Dec instead - so panto trips, visiting Hamelys, ice skating with oldest, winter wonderland etc. Hope to continue this as they get older rather than giving multiple gifts
No gifts for adults. DH and I randomly buy each other things throughout the year anyway and for Xmas we treated ourselves to a theatre trip and fine dining experience.
Loving reading everyone elses and getting more ideas for next year
