I ordered my cards today. My inspiration for the image was a kind of deconstructed hanukkiah, with nine candles arranged in more or less a straight line.
I like how peaceful and calm it looks.
I also like that it's not overtly for any holiday, really, but it won't look out of place in any Christmas card display.
My mother would approve, I think. Then again, she'll probably just be happy that I'm sending out cards at all.
