Fold the square piece of paper into two equal halfs, then cut along the crease so you get two rectangular pieces of paper. Fold each piece in half again along the longer edge to make the rectangles narrower, folding the left edge over onto the right edge. Fold each rectangle in half along the shorter edge to make the rectangles shorter,folding the top edge down to the bottom edge. Then unfold this step to leave a crease. Fold the bottom half of each piece up so that the side edge is now in line with the crease you just folded. Make the folds mirror images of one another, so that one is folded up to the right and the other to the left. Fold the top half of each piece down in a similar manner so that you form two opposing S shapes. Flip both pieces of paper over and notice that S shape has two squares at the end. Fold the outer corner of each square in along a diagonal to create triangle shapes. Then fold the triangle shapes over onto the middle section of the S and fold back to create a crease. Flip over one of the pieces of folded paper and rotate 90 degrees in relation to the other. Fold over outer corners of the bottom pieces triangles and tuck them into the pocket in the middle of the top piece. Flip over to create your star.
