How to Make a Triangle Box Out of Paper

For an easy and fun paper craft, think outside of the traditional square or rectangular box and experiment with a triangular shape. This paper box can be used for anything from gift giving to storing jewellery. You can create any size or shape of triangle and still get great results for a distinctly shaped storage space.

Draw a triangle on a sheet of paper. Then, draw two straight lines extending outward from the bottom edge of the shape. The length of these lines will determine the depth of your box. Draw two downward lines of the same length extending from the bottom corners. Then, extend the top of the triangle in the same way, using the same measurement. Finally, connect these outward lines to make a larger triangle around the first.

Cut out the triangle shape, making sure to cut along only the outermost lines.

Cut along each of the shorter lines to where they meet with the original triangle shape. Fold each edge of the shape inward along the line of the original triangle shape. Fold the ends of each side inward to make small tabs.

Fold the corner tabs of each edge inward, then fold the sides up till they're perpendicular to the bottom. Tape the sides together along the inside of the box. Pinch the corners to make crisp points.

Repeat steps 1 through 4, making the second box in the same shape as the first but a quarter of an inch larger on all sides. Fit the second triangle shape over the first to make a box.

Tip

Use construction paper or thin cardboard for a sturdier box.
