If you are looking for something fun and interesting to do with the kids over the easter break I highly recommend that you go and see "Hats an Anthology by Stephen Jones" at the Queensland Art Gallery. I went on the weekend with my mum (see kids and mums!) and it was fantastic! So many creative and amazing hats from different eras and designers...little sculptures for your head.
Best of all it's free and the kids can make their very own hats at the end!
The collection comes via the Victoria & Albert Museum in London....They even had the original Darth Vadar mask from Star Wars so you can take Mr Mum as well!
