If you’re looking for something a little different than the daily updated t-shirt blog, with a little larger and more in-depth articles, then you might want to think about checking out T-shirt Magazine. It seems to be a sort of portal, featuring articles, forums, a directory, etc. An example of what you’ll find in the article category is how to start a t-shirt collection.
It’s a pretty cool concept, with a little more meat to it than a standard blog. The magazine is updated every Friday and you can check it out at T-Shirt Magazine.
