UPDATE: FOR 2011 DIWALI IDEAS GO HERE!
Our school recently held an Diwali Social and we made 'diyas' to decorate the rooms.
The children were given a lump of clay, which they rolled into a ball (about the size of a large golfball), flattened a little, and then pinched into a little pot big enough to hold a tea-light.
Although I demonstrated the process, I love how they all turned out different. We used fast dry clay which hardened overnight (it is still VERY hot here in Dubai).
Next we painted the pots with acrylic paint and finally, glazed with pva glue and a pinch of glitter.
The children's diyas looked fabulous framing a rangoli design (made from coloured powder and glitter)
...and the floral rangoli
They even went up the stairs.
They took us 3 days to make but it was worth it.
Now they are ready to go home and I expect that many families will use them as Christmas decorations.
