Take a toilet paper roll and cut into half. Use pencil to draw a simple window on the paper roll.
Use a craft knife and/or scissors to cut the center, top and bottom sides of the window. Keep the outer edges of the window intact. Paint and allow it to dry completely.
Cut out the grass and flowers from colored craft papers. Apply glue along the bottom straight end of the grass cut out. Attach the glued part of the grass and flowers around the bottom edge of the toilet paper roll house, under the cut out window.
Cut out a circle out of colored craft paper, paint it with red paint and stamp white dots on the red circle. Cut a slit from the outer edge towards the center of the circle. Overlap the two sides of the slit and glue them to create a slight cone shape. This will be the roof of the toadstool house.
Cut out a small piece from the flexible part of a drinking straw. Attach the straw to the cone roof. Attach the cone roof on the top of the tissue paper roll house. Switch on an LED tea light, and place the toadstool house over it.
