Make round finials for dolls house fence posts (or bed posts) from appropriate sized wooden beads or glass topped sewing pins.
Here a sewing pin has been cut with wire cutters until only 1/4 inch of pin remains below the glass ball top. The pin is then inserted into the center of a post top, and painted to match the post. If you do not have the right sized pin, you can glue round wooden beads to the top of the fence post. The holes in the beads will need to be filled with wood filler.
