EDM Challenge #2: Draw a desk lamp or other lamp

Except for my stuffed giraffe leg lamp (which appears somewhere in Everyday Matters), most of my lamps aren’t that interesting to draw . So I unscrewed this new lightbulb and drew it instead. I tried drawing its contours as accurately as I could, stopping to see how each band of the bulb continued under the others as it coiled. It was a little treacherous.

I drew it with both of my Lamy Safari pens, broad and fine, but because it ended up looking a little meagre as just a line drawing I gave it a hit or two of watercolor.

I quite like doing these challenges, tackling each one at breakfast time, before the day gets going.
