I only use brown paper for gifts, which I decorate with paper stickers or use ink stamps and tie up with coloured jute string, so no sellotape. Advent calendar is a reusable one (11 years, still going strong) that contains a chocolate or sweets. I’ve more or less given up on Christmas cards except a few to elderly relatives who appreciate them. Decorations are either old or biodegradable. No plastic or glittery stuff.
Stocking fillers are practical or edible and come with minimal packaging - bamboo toothbrush, soap, nice socks or knickers, stationary, a book, lottery ticket, candle, chocolate.
We ask relatives to buy one, single item present for each DC rather than give piles of tat. Luckily MIL, DM and the aunties are good about sticking to that and checking what DCs actually want or giving experiences. Kids prefer experiences to “stuff”. Adults don’t swap presents anyway.
I’m 🙄at many “new traditions” of giving that require expense, like expensive gift containing advent calendars, Christmas Eve boxes (why?!), novelty deeply boppers etc and new Christmas PJs, so don’t bother. Christmas presents under the tree on 25th and a stocking still create impact with mine. We buy lots of delicious special food, locally as possible. Round me that’s dead easy.
