Stained Glass Windows
Have you any spare tissue paper lying around that you could use to create your own stained glass window? If not, you could use some grease proof paper and colour with felt tip pens to create the same effect.
Chalk Light Bulbs
Use different coloured chalk and an oval template on a dark background to create your own Light Bulb artwork. You could do this on black paper or a stretch of tarmac outside would work just as well.
