I love when a package is as pretty on the inside as it is on the outside. Like envelope liners and shopping bags with printing on the inside. I even love it when you buy a shirt and they do that fold on the tissue paper before packaging it up.

To make this, you do almost the exact same steps as making an accordion fold, except instead of doing equal folds, you make a slightly larger one at every other fold. Click here for the step by step.
