I learned how to weld on my own time to make a container that will protect my Free flying bird from the people of the New York Transit. So I made a steel frame and then wrapped it in brown paper. Next I bought some cheap duct tape and wrapped the box. This allowed it to have a strong stretchy material around the paper.
