Before I lay my pen down on a piece--or when starting a new pen--I test its flow, much like a doctor on a TV show flicking a needle before plugging it deep into a rolling, wormy vein or random part of thigh. This board is where that happens. If you're wondering why I'm offering this, some fine folks really enjoy the "process pieces." It is, behind the scenes, if you will. 5"x7" fountain pen on warm, rigid, cream matte paperboard.
