Cut out two purple trefoils of the same size, make a hole in the centre of one of them for a stem. Roll up a green stem, make small cuts on it's upper end and fold them outwards (for gluing). Insert the stem into the hole and fix it with glue. Curl down trefoil's petals using a pencil. Glue the other trefoil onto the first one, placing its petals so that they are rotated 60 degrees to the underlying ones. Curl them up. Then cut out a smaller trefoil with narrow petals, curl its petals and glue it into the flower, keeping at an angle of 60 degrees to the previous one.
