Instructions
Fold one corner to its opposite corner, flattening it to define the crease. Unfold the paper.
Fold the remaining two corners to one another, defining its crease. Unfold the paper.
Rotate your paper so that one of the corners points toward you. The paper should be a diamond rather than a square. Fold the two side corners and the bottom corner so they meet in the middle of the paper.
Fold the remaining corner backward so that it meets in the corner, but on the opposite side of the paper.
Fold the four new corners you created to meet in the middle on the side where you folded the fourth corner in Step 4. Flip the paper over.
Fold the bottom corner all the way up to meet the top corner.
Locate the two inner corners under your paper. Pull these gently, and they should swing outward with ease.
Take the top corner and fold it back down so it aligns with the two inner corners.
Tug the upper square toward your left while folding the right-hand side over to the left.
Pull the single inner point, and it should swing down and out with ease, completing the figure.
