design house™ greeting card templates are PSD files designed to WHCC folding card standards, which make them easy to customize and order. design house™ greeting card templates are designed for quick recognition and ease of use. Like the design house™ actions, layers are clearly labeled and organized with the designer in mind. Every design house™ greeting card template includes a design for every side of the card, but does not require that you use those designs. design house™ greeting cards are not part of the design house™ libraries.
