For the creepy eyes, first prime Polystyrene balls in different sizes with white Acrylic paintand let the paint dry well. Now paint medium sized circles in different colours on Polystyrene balls.
After the coloured circles have dried, paint a smaller circle in the middle of the coloured one with black Acrylic paint. Set light reflections with a thin white Marker and draw with a red Marker some veins in the eyes
Turn two chenille wires in different colours to form a Cord together and fix the string with a little Handicraft glue in the back of the Polystyrene ball.
Then place the eyes with some flowers in a matching flower pot or vase and use them to decorate tables or chests of drawers. These polystyrene eyes will also make a great impression on the windowsill and can even be admired by strollers.
