CARDS BY CARRIE BRADSHAW: Actress, designer, perfumer, Web site curator — Sarah Jessica Parker has done it all. Hot off the heels of her debut footwear collection and gig as guest curator of WeTheAdorned, the “Sex and the City” star is entering a surprising new market: greeting cards. Parker unveiled the project, a collaboration with Hallmark, on Thursday afternoon, citing her “love of the written word” as inspiration for the collection. “I love cards, I always have,” Parker said. “I’m a big believer in the power of a hand-written note, so I was very interested in being involved with this project.” The designs, which will hit Hallmark stores in the coming week, cover a range of occasions, all largely embellished with glitter, gems and other girly fodder. The line will also include stationary and giftwrap.
