For this invention all you would need is a post it note, color pencils, and a phone. The first thing you should do is write a positive message that is colorful on the post it note. Next, you should face time a person and show the message on the screen so that they can read it. The reason you should do it through face time is so that you are able to see and hear their reaction. Even though from them just seeing you can make them feel happier. Lastly, you should do it through face time because you would be able to have a full conversation with that person.
