Don't be afraid of salt and pepper. Every dish is improved when you add them. This doodle
is from my sketch-book. I adore micron pens and use them all the time. My family hates them because when you write or draw you have to hold them straight up, otherwise the tip of the pen goes all askew and then the line is blurry. There are a variety of tips available for thickness of line.
Next time you "doodle" - take along a micron pen, a sketchbook, (a napkin will do in a pinch) and add a grain of salt to your day, or spice it up with the twist of the pepper mill.
sel et poivre please!
