The expression, "A simple thank you would have been nice," has always baffled me. To me, there is nothing straightforward about saying thank you. When I'm genuine, I want my expression of gratitude to be as tastefully embellished as possible — like a letterpress card.Luckily, stationer Linda & Harriett has made the gesture simple for me, by unveiling some new box sets of thank-you notes in elegant scallop, lace, and swirl prints. Each card is letterpressed with soy-based ink and features the calligraphy of Brooklyn-based Jenna Hein. I'm thinking the swirl pattern is my favorite; I can just see the personality oozing off the 30 percent postconsumer waste paper. A set of six retails for $14.
