I think lots of people are in the same boat this year, but we'd like to simplify Christmas. We have started by chatting to friends and family about reducing gifts, and in some cases giving cash (children). So have very few people to buy for, and everyone left we is immediate so I'm not worried about buying things for the sake of it. Good start!
I can't resist buying new decorations (in addition to existing ones, not to replace them) but instead I'm planning on going to a fancy garden centre/barn type place for the experience and buying one or two small things. My downfall is probably online browsing, and I tell myself it's fine as I buy quality and long lasting products, but there's no reason I need more! So yes, avoid that.
Cards - family and close friends only? I find it difficult with work as some of my colleagues come under the good friends category and some I haven't known long and you can't really only give to some people.
Food - this is very hard for me. I am on a perrenial diet but tend to go mad on holidays/Christmas so when I'm hungry in autumn I start stockpiling treats for Christmas which is frankly ridiculous. I don't host due to space but try to take on a fair load with my mum, I do buy too much. The past few years we have been very happy with good ham, bread and a bit of cheese for our tea, so do we really need all the other bits just in case?! Probably not.
We don't do big expensive events but will catch local free events, the Christmas tree festival in our local church was great last year.
I do love Christmas and we are frugal (in terms of money and food) throughout the year so I don't want to restrict if you see what I mean.
What are you doing this year to simplify?
