Draw a flower shape in the center of a paper plate using your white crayon.
Paint the paper plate in your choice of watercolors.
While the paint is drying, make the stem for your flower. To do this, cut a long strip out of a full sheet of green cardstock. Cut out a couple simple leaf shapes too.
Glue the leaves to the stem and once the paint is dry, glue the stem to the back of the paper plate.
