Honestly, I did this just because it seemed very easy, just a few strokes to a well-formed girl! I did this during a long-term holiday, when everyone else went home and I was alone in the hostel, too lazy to do much. My room was as clumsy as ever. I just tore off a page from my Maths notebook, rummaged in my messy corner of the room, for a brush, and green was the only color I found!
