Blank Note Cards are always handy to have around! Many of our clients use only blank cards and write all their own notes.
Message Inserts in blank note cards give you complete flexibility. Choose the card design that you think would appeal to your client and insert the message that you think would speak to the owner's heart. (How do you know which one? Imagine that your client is standing in front of you, and imagine yourself saying the words of the message to them. If it seems like the right words, go for it. If it just doesn't feel right, use something else.)
Sometimes no printed message is really going to be right. For those occasions, you'll have a stash of blank cards to write your own note. And remember, especially in the case of a sympathy card, you don't have to be fancy, just be sincere.
