I’ve been going back and forth on how bold to go with our dining room. On one hand, it’s the one place where guests actually sit and look around for a while, so it feels like a good opportunity to do something special. On the other, I don’t want it to end up feeling like a restaurant theme wall. I like the idea of an accent wall, especially behind the table, but finding the right pattern that feels intentional and not too trendy is tricky.

I found this art deco self adhesive wallpaper from https://fancywalls.eu/wallpaper-pattern/art-deco-wallpaper/. and ended up using it with warm lighting and darker wood furniture — turned out way cozier than I expected. Might be a good option if you're aiming for atmosphere without going over the top.
