Cardboard letters with foam (from Michaels or Joanns) - stack, glue and spray paint for super cute decor. Covered in glitter or silver thumbtacks to spell: "God is Love." Have "God is" in smaller letters. "Love" in bigger letters with the flowers.
I love you clothes pins: Write a message with a FINE POINT sharpie so it doesn't smear. Write "I love you" on a paper. Cut it out, and hot glue it to the clothes pin end. Would be cute for a care package!
