Holiday cards were always a special part of the holidays in my family growing up, a tradition that I carry on with my own little family. I always enjoy sending a little holiday greeting and family update, and likewise, I look forward to receiving cards from family and friends. Holiday cards are a great way to cap off the year and are an opportunity to more formally wish family and friends the very best. Holiday cards don't have to in and of themselves be formal though; like any custom correspondence they should be an authentic representation of the individual, couple, or family sending them out.
