In order for the children to demonstrate how they would cross the road I created a series of character that they could use. I created two children and two adults, with the intention that the user could choose a character that represented them, and that they would always have to pick an adult figure to help them cross safely. I did not create initial sketches for these characters as I wanted them to look as freehand as possible in order to successfully copy a child's style of drawing. I created them entirely on Adobe Illustrator.
In addition to these stickers I also created some simple fastening stickers to hold the leaflet together when being posted, using the same colour scheme and silhouetted shapes.
