1. Paint the bottle first with beige color and then take your brush and dip it slightly in brown paint. Brush streaks of brown paint on the wet beige paint to create thin vertical stripes. Set aside and let dry. In the meantime, paint the half styrofoam ball with red paint. Most likely it will need a second coat so when the paint is dry, paint it again. Once the second coat is dry, paint a coat of beige und the flat side underneath and let it also dry.
2. Now you can glue the styrofoam half ball to the bottle. Press them together from time to time. Once the glue is dry (this can take a while), take the white dimensional or puffy paint and make white spots on the top of the toadstool. Let it dry. If using puffy paint, then you can take a hair dryer to puff it up a bit.
