1. The first step is spelling flowers: white center as the bottom layer and yellow center as the top layer. Move the white edges to the top yellow surface. Make small flowers.

　　2. In the first case, the white prism is on the bottom white surface and directly turns 180 degrees.

　　3. In the second case, the white edge is on the side of the middle layer, so push it directly to the top layer (please note that if there is a white edge in the pushed position, you need to rotate the top layer to get out of the way).

　　4. In the third case, the white prism is on the bottom side, and the white prism is facing itself. The front side rotates 90 degrees clockwise to make the white prism in the middle layer, and then operate according to the second case.

　　5. In the fourth case, the white prism is on the side of the top floor, and the white prism is facing itself. The front side is rotated 90 degrees clockwise to make the white prism in the middle layer, and then operate according to the second case.

　　6. The second step is to change the floret into a cross

　　7. Rotate the top layer so that the side of the white prism is the same color as the center of the side, and then the center of the side is facing itself, and rotate it 180 degrees clockwise, so that the white prism changes from the top layer to the bottom layer. This method is used until the cross is made.
