You will need:
Large cardboard box
Box cutter or craft knife
Hot glue gun
Metal straight edge
Gold spray paint
Paper lantern template (Download PDF here)
Take a cardboard box and cut so that the entire box lays flat and there’s a large surface to work with. Use the template to measure and draw each piece of the lantern on the flat cardboard. Cut out the lantern design using a box cutter or craft knife. You should have 4 of Piece A (side panels), 8 of Piece B (triangles), and 1 of Piece C (top panel).
To score the sides of the box, take your craft knife and apply half pressure along the middle corners that are going to be folded to create the lantern shape. Fold the scored corners of Piece A and hot glue all the open sides together. Hot glue the triangles (Piece B) to the main body of the lantern. Cut out the top piece, but wait to attach it until the end.
When all pieces are connected, prime the cardboard with white spray paint. Once the coat is dry, add a top coat using metallic gold spray paint. Don’t forget to paint the top piece, too!
Once the paint has dried, take the colored tissue paper of your choice and cut enough so that it will cover the window shapes of the lanterns. Reach inside the lantern and hot glue the tissue paper to the open windows.
We used an under-cabinet LED strip to light our lantern, but any battery-operated LED light will work. To create the light fixture for your lantern, tape twine securely to the back of the LED strip, then hang the light in the lantern to measure how long you want your twine. Cut the twine, leaving about 1 inch extra. Pull the twine through the hole in the top piece of your lantern and tie the other end to a popsicle stick or wooden dowel.
Finally, place the LED light into the lantern and secure the lid tightly on top. Now sit back and enjoy the beautiful glow of your handmade cardboard lantern!
