Cut two strips 1½ inches (4 cm) wide by 8 inches (20 cm) long from a piece of origami paper.
With a tape measure or ruler, mark the halfway point of each strip—in both width and length—with a pencil on the side of paper without the pattern.
With the pattern side down, form an X with the strips, making sure your marks from the previous step overlap. Glue the strips together where they intersect. The square in the middle of the X will be the bottom of the box.
Fold the arms of the X to make a box, unfolding and creasing carefully.
On a protected surface, use a craft knife to cut a small X in the bottom square.
Use paper punches to punch out fun designs in each arm of the X. Be careful not to punch holes on the creases.
Assemble the box by folding two side strips up on the creases to form a top square. Glue these pieces together. Then fold up the next two sides to join the top square. Glue them all together. Let dry.
Repeat above steps to make enough boxes to cover each light on the string.
Before hanging, gently push an LED light through the X in the bottom of each box.
