We found out about designer Tara Hogan of Ink & Wit from fellow blogger Holly Becker (Tara designed Holly's new business cards). From there, we found a Tara's great set of baby postcards from her paper design studio, Ink & Wit. She likes postcards because she wants to help conserve paper and also postage. You'll love them for their usefulness and simple elegance for any correspondence occasion.
