This is an excellent silkscreening tutorial by Shannon Gerard on No Media Kings. Really, it's very good and in depth. Plus No Media Kings is a great project by Jim Munroe the author of the excellent "Flyboy Action Figure Comes With Gas Mask" that I know I have written about on this blog before. I checked that book out of the library, read it, loved it and checked out all of his other books. And now he is giving that book away in e-book form on his site. I also loved his book "Everyone in Silico".
