I have become a big fan of Blondie Designs' cute illustrations and color choices. Both the artists, Angie and Kristin, gradually cultivated their love for beautiful typography, soothing colors and elegant design. Another feather in their hats is that they are the Senior Art Directors for Martha Stewart Living magazine and Martha Stewart Weddings magazine!
The owl bookplate (shown) is from their Owl Collection. There are also note cards, invitations and labels available in the same print.
Visit their blog here for a closer look at their work.
