Have you heard of Go Green Girl.net? Well its a funky organic tee shirt shop based in the USA. They feature tees with earth friendly sayings, and each tee is 100% green.
There has been an explosion of online tee shirt shops as of recent. You have plenty to choose from. What i like about the Go Green Girl tees is they have funky hip designs, with swirlies and what not. The t shirts are made with water based inks, and made in the USA.
Their prices are reasonable as well, with each green tee averaging about $30.
