Begin by turning the tissue box upside down. Open both ends of the tissue box, and cut along the top seam/fold of the box, approximately 1”, on both sides.

Fold the sides back in, and fold the top flap over, and hot glue back together. The sides of the tissue box will now be slightly rounded, and your tissue box should be shaped similar to an igloo.

Next, measure and cut the poster board to fit across the top of the tissue box, and adhere with hot glue. Cut another piece of poster board to fit across the front rounded portion of the tissue box, right above the “door” opening, and adhere with hot glue. 

To make the tunnel entrance you will need to cut a strip of poster board approximately 3-4” wide. Fold the poster board around the “door” to measure how long you will need, and cut accordingly. Make a ½” fold the length of the cut piece of poster board, and then cut small slits all the way across the fold, spacing the slits approximately 2” apart.

Using hot glue, attach the poster board around the “door” of the tissue box, using the cut slits on the fold to help curve the poster board as your glue. Your tissue box should now be in the shape of an igloo, with a tunnel entrance, and dome shape. 

Lastly, using the glue gun, attach cotton balls all over the tissue box, making sure to cover all sides and the tunnel entrance. Let the glue dry, and your tissue box igloo is ready for play!
