I love the marriage of word and image that takes place with greeting cards and inspirational or aspirational decorative art. I look at it like a modern day equivalent to illuminated text. It's a pure synthesis of illustration and written word, and I love playing around with it whether the message is sweet or sassy, tender or playful.
Wordless images can speak volumes as well, and for greeting cards are especially useful. No one can say it better than you, but the image can help set the mood.
