It doesn't have to be exactly this size, you can use a random long strip of paper. The first folds will make a 60 degree angle, so you can divide the strip into equilateral triangles. At the end, change the direction of the folds for the last 5 triangles (4 to cover all the sides, 1 to lock by inserting it under the layers) | Jo Nakashima | Facebook
