There are many things a person can say on a funeral flower card including "With our deepest sympathies." When wording the card, the writer should be sensitive and ensure their message is heartfelt.
While the message can vary on the card, users should not state that they know what the receiver is going through. The writer can say they are thinking of them or that they are here for them in their time of need. The exact message will vary depending on the sender and the relationship of the person receiving the card. The message can be short, or it can be longer.
