Taylor Swift is getting ready to launch her signature line of cards for American Greetings, which should hit stores in mid-February. The 20-year-old singer-songwriter wrote the content and helped design the cards, one of which uses her signature hand heart.

"I've always been fascinated by how we express feelings to each other," Taylor tells US Magazine. "My idea of a great song is a song that says how I feel, better than I could. I feel the same way about cards."

In addition to Taylor's cards, which range from birthday greetings to love notes, the enterprising superstar is also expected to create a line of stationery -- which she says she loves getting as presents -- as well as gift packaging.

Next up for Taylor is a performance of her new song, "Today Was a Fairytale,' from the upcoming 'Valentine's Day' soundtrack, on this Sunday's Grammy Awards telecast (Jan. 31). She's nominated in eight categories, including Album of the Year for her sophomore effort 'Fearless.'
