Connection cards are a set of three cards stacked within each other (think Matryoshka Russian Nesting dolls). Inside each card is a written prompt, whether you use it to start the letter yourself or use the prompt as a question to your correspondent, it is there to spark a deeper connection. Questions range from topics of animals to grief and everything in between. While you can choose to use the cards any way you want, a personal recommendation is sending all three cards to one person giving them the option to write you back or write another listener. This way the rope of connection grows stronger each letter sent.
