Step 4: Fold it up

Picture of fold it up
Fold all the tabs on the right side along the dotted lines. Then fold along the center dotted line.

Next slip the four vertical tabs into the respective cuts in the back panel. The last tab acts as a way to close the CD case. The corners of it slip into the diagonal slits in the back panel.

Now's a good time to crease all the folds very firmly.
