Green Party Watch has an excellent YouTube which lasts seven minutes and 51 seconds, on how to organize the paperwork for an Illinois ballot access petition. The “show” stars Phil Huckelberry, state chair of the Illinois Green Party, as he fastens loose petition sheets that have recently been collected to get Tom Tresser on the Green Party primary ballot for Cook County Board President. See that particular blog post from Green Party Watch here.
Illinois requires the petition pages to be fastened together, and the video shows how that is done. The filing must also include a Declaration of Candidacy, and for candidates who are running for state or local office it must include a Statement of Economic Interest.
