Despite how many I make, sketching still lives is not my favorite thing. Apples and avocadoes are not particularly challenging to draw, so I don’t do them for drawing practice, but they are very challenging for practicing form, color and light. (They could make good compositional practice, too, if I ever stacked more than a couple of apples at a time.)
Sometimes I like to sketch the same piece of produce twice – once in color; once in graphite – because I learn different things when I have color and when I don’t. I find shiny fruit easier for conveying form because I can rely on the bright highlight to do a lot of the work. The avocado with its dull, bumpy skin was much harder.
Sometimes I just crave using bright colors, and the gray winter landscape just isn’t doing it for me, so a tomato and a banana keep me happy. Mostly, though, still lives entertain me when it’s too wet to play outside.
