Fold the point on the top left toward the top right corner. Turn your paper and repeat the folds on the other side. Unfold the paper to reveal the creases. Pinch the sides of each X to form triangle bases."

Set the piece of paper on a flat surface in front of you so the long edges are on the sides. Fold the paper in half lengthwise so it looks like a hot dog bun. Make sure the edges and corners line up before you crease your fold. Make sure your piece of paper is vertical before moving on. Grab the top right corner and fold it toward you. Line up the top edge with the left side of the paper underneath. Press along the folded edge to crease it. Your piece of paper should look like a rectangle with a triangle on top. Take your time to make sure the edges are lined up when you fold your paper. If you crease the paper and the edges are misaligned, your spaceship may not fold together as easily. Take the top corner of the triangle and fold it over onto the piece of paper. Line up the folded corner with the top right corner to make a smaller triangle. Press down along the fold to make a crease. The edge that you folded over should form a straight line on the bottom of the triangle. Rotate the paper 180-degrees so the triangle you just made points toward you. Fold the top right corner so the edge lines up with the left side of the paper. Then, fold the point of the triangle down so it’s lined up with the top right corner. Make sure to press along the folds to crease them. Undo the triangles you just made and flatten the paper out again. You should see creases forming an X-shape on each side of the paper. If the creases aren’t visible, try folding the paper again and press down harder along the edges. With the piece of paper vertical, grab the left and right sides of the creases with your thumb and index finger. Pinch your fingers together and pull the top edge of the paper over them. As you fold, the sides will collapse inside and a triangle. Turn the paper around and do the same to the other side. If you have trouble pinching the sides in, fold the top edge of the paper so the crease goes through the center of the X. Unfold the paper and try pinching it again.
