I loved this and thought that its such a great idea! Another thing to do is to take a regular sticky note and write "You're beautiful pass this note on" and give it to someone in school, at the bus stop, anywhere!
This could be a good idea for youth lesson on blessings. Or make a knot for every problem/diffuculty you may be facing and then go back and untie the knots while listening for Gods answers in meditation. Letting the problems go to God.
