Taylor Swift has teamed with American Greetings to create a line of greeting cards, gift packaging, stationery, online photo personalization products and online greetings that will be available worldwide in the spring. "My idea of a great song is a song that says how I feel better than I could. I feel the same way about greeting cards," said Swift. "I've always been fascinated by feelings and how we express them to each other. Getting to write and design these cards is a wonderful experience."
