If you thought you had your holiday cards under control, think again. Mary-Kate and Ashley Olsen have teamed up with Paperless Post and three fashion bloggers—Beckerman Biteplate, My Closet in Sketches, and Paper Fashion—on a series of artsy holiday cards, which are being sold under their Olsenboye label. As you may know, every Olsenboye collection takes inspiration from a different global location. This season, the Olsen twins are taking inspiration from Russia, so each card has a Russian theme. The best part, however, is that these cards are free to send! So, what are you waiting for? Click through to PaperlessPost.com to send your favorite card to your favorite friends!
