I love a bit of craft, especially if you don't need lots of expensive stuff. I have an autistic teen and they like to join me for a Christmas film and a bit of crafts so its a way to get them out of their room as well.
I've tried the paper stars here: https://awonderfulthought.com/how-to-make-paper-stars/
I always make these woven heart baskets as well. They are very nostalgic for me.

I would love other suggestions.
