Read the story attached below called 'The Invisible String' or you could listen to it here... https://www.youtube.com/watch?v=2rZNTFf35Aw
"A wonderful story about how being apart from those you love doesn't mean you are all alone. When you love someone, you are always connected by your invisible strings. It helps children manage feelings and navigate difficult emotions."
You could make some beautiful heart crafts for your family or friends that you are missing. You could then attach the yellow card that explains that you and the other person/people are connected by an invisible string. You could send these hearts to your family or friends.
