To make an origami rose first crease a square piece of paper along a diagonal and with the help of the diagonal fold the paper in a diamond shape as shown in step 1. Fold the corners of the diamond shape. Flip it and repeat the same. Bring the upper corners downward on both the sides. Make a star shape from the folded paper by taking and pressing all the four pointed shapes in opposite direction to each other. Fold all the petals inward. Flip it over and raise the center with the help of your fingers and fold along the creases. With the help of tweezers pinch the center of the rose and turn it clockwise to get a swirl in the middle.
