I just updated my first post mentioning that I'm Jewish. A *lot* of the curlies on this board are either Jewish or atheist, or at least likely to feel a bit offended by a "praise Jesus" ornament. (Or Muslim, Buddhist, pagan, etc. And is pagan actually supposed to be capitalized? I feel like it's not, but I'm not sure.)
I think cards and wrapping paper are no biggie - I wouldn't want someone to go buy new paper just for me, and Santa paper can be super cute! I've also been given ornaments before - as I mentioned, I celebrate with my stepfamily at their house. So I have some Hanukkah Christmas tree ornaments - perfect!
