We used a grid to help us enlarge our avatars and keep the correct proportion. We then talked baout what we want to exaggerate about ourselves. Often we focus on the things that we do not like rather than the things that are good about ourselves. I have then make a list of the things they love about themselves and things about them that they want to exaggerate. These are written in the background of their portraits.
I absolutely love how these turned out! They did a fantastic job enlarging something that started so small to something so big! They got a kick out of seeing our 3 and 4 year olds seeing these large portraits out in the hallway. For some reason they were mesmerized by these portraits!
