Whenever I paint I long still-life I always over-buy fruit. I find it useful to use some of the extra to paint a Mini while I'm working on the larger piece. I had plenty of the green grapes left and thought they would look great next to the purple of the plum. When I first painted the grapes in the other piece I found them a bit boring to paint. When they sat out on the table however for a few days I found the colors to be much more interesting.
