This is a pencil case that has a little style. When I was a child, I use to make one of these before I started school since the sixth grade. I still make these just for fun.
For the case run around and collect the following necessary items from around the house (especially your mom's sewing box): Cardboard, elastic, needle and thread, scissors, tape, string, glue. For the contents of the box get the basic necessities such as: color pencils or crayons, pencil, pen, eraser, pencil sharpener, rule and circular ruler.
