I like messing about as you know. In this case it’s a butterfly drawn with nail polish. I also used some felt pens to fill in the gaps. Yes it’s a bit strange, but I prefer doing this to just throwing the stuff away. At least the nail polish is locked into the paper and not sent off to landfill somewhere.
I will carry on doing drawings with them till they run out. They could be used to do illustrations. I wouldn’t use them in a children’s book! It might give them the wrong ideas and I am careful to apply a bit at a time to reduce fumes.
I did draw with boot polish once as part if a mark making class. It’s amazing what you can do…. Didn’t JMW Turner add mud and sand to his paintings?
