This document provides instructions for making a heart-shaped box from a single sheet of paper. The instructions are divided into two sections - one for making the base and one for the lid. To make the base, the paper is folded in half lengthwise and various mountain and valley folds are made to create the shape. Tabs are tucked into pockets to form and lock the shape. The lid instructions follow a similar process of folding, shaping, and locking tabs into pockets to form the lid of the heart box.
