SketchType is a variety of original hand-drawn type sets created by The Organic Type. They are not keyable fonts. They are photoshop images which would need to be individually hand set and composed. Their reason for this is that digital fonts don’t provide the subtle gradations that the images can.
I think some of them are beautiful and would add charm and personality to anything they are used in. Over the next few weeks I will try and create some of my own.
