The Art League
The Art League, founded in 1954, is a charitable and educational nonprofit organization devoted to promoting and maintaining high standards of fine art in the Washington D.C. area. The Art League seeks to stimulate and encourage artists by operating a gallery with many opportunities for members, including monthly juried shows of members' work, other chances for exhibition of work and many educational possibilities. The League is a multifaceted visual arts organization that meets its mission through its gallery, fine art school, and arts-outreach programs.
I've been using Koh-I-Noor Rapidograph Technical Pens since 1969. My aunt bought me my first set when I was 12 and I have used them daily ever since. I love the fact that I can mix my ink colors to match my watercolor or my wardrobe and use "Pelikan Drawing Ink A" almost exclusively. Though the inks made by Koh-I-Noor and Winsor Newton are satisfactory.
If you are a beginner, I would NOT recommend purchasing anything smaller than an 0 (0.35 mm). Even as a professional I find cleaning a 4x0 to be a challenge. I work most often with a 2x0, and find them to produce the smoothest flow, if kept clean.
