Love letters may be lighthearted or express one's deepest feelings. No matter the occasion, the letter should be sincere and written from the heart. While it may be intimidating to express one's innermost feelings in a letter, it is rewarding to know that true love letters will be cherished forever by their receivers.
Love letters should be handwritten.
Presentation is everything (consider using wax seals, ribbons and specialty/decorative papers).
Employ simple, honest and emotion-filled communication.
