Interesting article on Rosh Hashanah cards:
An Exploration of the Rosh Ha'Shana card

My husband sends out Rosh Hashanah cards to many friends and relatives (even the non-Jewish ones) as a counterpoint to "Christmas cards". Sometimes, the cards don't go out until Sukkot or so, as I think will be the case this year since I don't think he has started yet. He insists on writing a personal note on every card and for people we really care about keeping in touch with, he sends a mini photo book that he puts together from photos of our family's activities of the past year. The books are about 2" x 3" with about 24 photos or so---no captions, but he says that if people don't know what a photo is or are intrigued by an interesting or mysterious activity, then it will motivate them to call us. The photo books cost just a few dollars each if he orders at least 50.

My Jewish friend started sending me Rosh Hashana cards when I converted, and when I got it this year with two babies on it, i realized I'd grown up enough that I probably should make some, so I did. :) I only sent out like seven because I got a pack of ten and had to be stingy because the synagogue gets all huffy if someone doesn't get equal treatment.

I'll probably send the rest of my friends Thanksgiving cards. My best friend's family (who are Christian) do this, and I like it.

We send personalized ones out to close friends.

I've sent them out in past years but last year I made Chanukah cards instead. This year...I'm not sure. I guess I better decide.
