re: How do you become part of a collaboration?

You can always come up with an idea and start your own collaboration. Ask people whose work you admire to join you. You don’t have to wait to be asked and don’t feel like your work is not good enough. Collaborations are generally made up from all different skill levels. You just bring what you can and it will be great.
