a good ahb logo..the hop vine and writing with the www.aussiehomebrewer.com.au on the sleeve.
ive posted a few pics of the grumpys(hope you grumps dont mind) shirt as not all of aussie brewers have seen them but may give a few ideas.
Big D i think thats a great example of what Ahb shirts should look like personelly... as the grumpy's shirt is something you can actually where out for a meal or a special occasion.
This i think would set of Ahb is having as others said the hops emblem with Ahb and as Big D Has said on the sleves the Ahb url
Using the tshirts that i think Keneasy post are not a tshirt that you could actually wear out and feel your promoting in a sense the ahb forums (no offence Keneasy as i could wear them around the home on brewing days)
The thing is keep it simple and i think it would look the goods and by using a simple emblem like grumpys has on there shirts the emblem can be easily incorparated into the hats as well if Fiscus wishes to go that far
well for what its worth wearing the grumpys shirts out and about certainly raises some interest and favourable comments.
for grumpys behalf i reckon it raises there profile to no end.
besides black shirts go with anything and if you love your food like me then they also hide stains well.
