I think it is more a walkthrough than a How to, but I hope it will help you to understand the Torn Paper Technique in a better way.
By the way it is also possible to make it in a larger way ... on A4 pages and others.
First it is always necessary to do a sketch of the figure you want
Torn the papers you want to use and then put tons of glue on the card and afterwards all the paper pieces on the glue ...
Press a bit with your fingers, so the pieces gonna be fixed to the paper.
Cut the figure you have made and glue it on another piece of paper.
The same I made with the balloons and just put some yarn to the dodo ... so it gonna be fixed to the balloons.
