Mattias Adolfsson is a Swedish illustrator who uses fountain pens for detailed drawings. I became enchanted with his work via Fountain Pen Network ten years ago when he posted a drawing done with a Namiki Falcon and Diamine Monaco Red. The duo is lovely for drawing and elegant for shading as well as simplicity.
Sometimes I let the nib release a little extra ink and move it around with a swab, toothpick or small brush. Otherwise, the expressive line from the nib is gorgeous on its own. Any ink will do, though J. Herbin Lie de The is an especially good alternative. My Stillman & Birn Sketchbook loves the attention and with Mattias for inspiration, it’s a win-win activity.
Tools mentioned are available at Amazon: Pilot Namiki Falcon SF, Stillman & Birn Sketchbook, Diamine Monaco Red, and J. Herbin Lie de The.
