I really like fountain pens and the huge variety of inks, nibs, styles, and the things you can do with them that you can't do with an ordinary ballpoint/felt pen. There are many advantages to using a fountain pen, and some disadvantages. One of them is, if the ink is too wet you can smear or cause transferring onto reverse sheets of paper.The rocker blotter is a traditional device used to hold blotting paper and let's you easily pick up the excess ink from your writing without the smearing. You don't slide the paper across the writing (which would smear), you place the edge down and rock it across.This video gives a pretty good overview, and that's where I picked up my strips of blotting paper (no affiliation): http://www.youtube.com/watch?v=JGsOU1EJumcFiles removed per overreaching Terms of Service and in protest of Makerbot's anti-open source stances.
