From their About page:
Friends of Type features original typographic design and lettering – fresh visual content – practically every day, by the four primary contributors. Posts are meant to log ideas, express ourselves, and inspire each other and our readers. The last week of every month we feature a guest designer, someone we admire and think will elevate our work and the site through their contribution.
This is a sketchbook, an archive, a dialogue. The posts are sketches and ideas on visualized language; a collaborative habit born out of the realtime interactions that made us friends in the first place.
You can buy prints, or hire them if you need their skills.
