Templates for social stories

Does anyone know any good websites where I can design social stories or visual aids to help an autistic child understand their daily routine and what is going to happen each day?

When I worked in a SEN school I remember these social stories with little drawings in red boxes on a page that explained step by step what was going to happen each day and what our daily routines are. I have a clear picture of them in my head but cant find any blank templates online where I can design something similar 

If anyone knows of any websites or resources that would be great
