I did a post on a collection of Twitter T-shirts sometime back. There are some cool tees in that collection, but if you don’t like them then you can create your own Twitter T-shirt. Yes, you can create your own Twitter t-shirts easily with the following sites.
140tees
140tees lets you create your own Twitter t shirts in just three steps. First you need to choose a tweet to print on the tee then choose your Twitter t-shirt and customize the design and finally make payment.
Twitoshirt
Twitoshirt lets you create your own Twitter tees by putting your favorite Twitter status message on them. Juts enter the URL to your favorite Twitter status message and customize the design and buy the resultant t-shirt.
