I love drawing with fountain pens. There’s something very old-world intriguing about them, they’re wonderful to hold, and they produce rich lines with occasional unpredictabilities and surprises. However, they are writing instruments rather than drawing instruments. Fountain pens are designed for controlled fluid up-and-down motions rather than random aggressive side-to-side motions. When they work, they work great, but every now and then, the aggressiveness of fast sketching on bouncing trains can occasionally cause the ink to skip and even stop flowing, as was the case here.
