We trade and receive a lot of shows and this system is the one we've created to help keep thing organized. Again, it takes nothing more than folding a piece of paper in half.

1. Create the cover information and/or artwork and print it out. A simple PDF template is available here
Right click to save the PDF file

2. Fold the print out in half.

3. Flip over and fold the right and left hand edges in. Secure with tape.
Want nicely creased edges a la crazy Martha and don't have a bone folder on hand? Use a credit/supermarket/library card instead!
