Notre Dame Prep students are tying ribbons around trees to honor Pope Francis' visit to the United States.
The ribbons represent a person's 'knots,' or problems, that are referred to in Pope Francis' favorite work of art, "Mary, Undoer of Knots."
Tuesday's knot-tying and prayer service was focused around getting young people involved in the Pope's message.
"It gets everyone involved, and it gets everyone to know who Pope Francis is, what he's doing and what his message is, which is important for all these girls to know." Emma Blanchard, a student at Notre Dame Prep, said. "These are hot button issues that Pope Francis is talking about and wantts to make a difference with."
Later in the week, the students will untie the knots, symbolizing their role in easing the pain and suffering throughout the world.
