      A double headed arrow means you need to fold and unfold. This weakens the paper slightly, leaving a crease.

      The Squash Fold is very common in origami and paper planes.

      The Outlined Arrow means “push.” It is telling you to apply pressure to the paper, along a given direction. In this case, it refolds a previous valley fold, while creating two new mountain folds.

      The Inside Reverse Fold is also very common.

      It usually follows a crease, created by a previous fold and unfold.

      Now, push against the center, creating mountain folds on both sides.

      The Pivot Fold involves moving a flap of paper around a set point, then re-squashing in another position. This fold begins where the previous one left off.
