So a really funky tshirt like this:

would cost you about 175/- plus shipping! and another old tshirt of yours. And these old tshirts will then be given to some NGO's so it will actually clear your wardrobe for good!
Really cool scheme!
I love T'shirts. This is a place for those who would like to discuss the latest and funkiest in tees over their morning cup of coffee.

I have already mentioned that I am an astronomy freak too, so just went looking for astronomy tshirts. Found this one on Cafepress really cool. There is also another ash grey colour available in tshirts and sweat shirts.
There is also another very cool astro tee available at zazzle. It has a pic of saturns shadow.
