I actually did this one for last week’s post but I wasn’t happy with it so I painted the apple and ended up using that instead. I hadn’t liked how controlled this one was, but now that I’ve had a week to look at it I think I’m okay with it.
I also used the (up to now unused) white watercolour paint for some of the highlights in the glass. Up until now I’ve just left highlighted areas as white paper in my watercolours. I think (for me anyway) the trick with white watercolour paint might be the same as it is with acrylic paint—use it sparingly.
