*great coffee places. I live in Melbourne so of course! But I don't live in the trendy 'inner' but where I am there are hidden gems like a place in Beaumaris called Gypsy - sorry,no weblink - but its this funky place with music, a fire, and just a beautiful environment
*I'm a little obsessed with http://soulemama.typepad.com/.I want that life! Wow she's an inspiration and a joy to read. I did lots of crafty earthy stuff with my kids when they were little. I love reading of her adventures - it takes me back to a time when the kids were little and we had sooo much fun! (not that we don't now but teenage is a whole different kind of fun!
