My dad always kept a notecard in his pocket, and on it were the names of all the people he is praying for. Since his death last year, I am carrying on the tradition. It is amazing how many times a day I stick my hand in my pocket-at home and away.
I love the yo-yo idea. You don't need to have the printed ribbon, just explain the significance of the ribbon, and end your talk with "forget me not". so wonderful of you to share your thoughts with the audience craving info. God bless.
