What's an Instant Gratitude Card? Well, how often does someone do something really nice for you and you find yourself looking for an immediate way to say thanks? We created Instant Gratitude Cards just for moments like these! They are small enough to carry around in a purse, but big enough to make someone's day. These mini Instant Gratitude Cards also make cute gift tags when tied to a bottle of wine or a batch of cookies as a hostess gift.
