My pencils were getting kind of dull so I had to sharpen them all, but it seemed suck a waste to just get rid of the shavings of woodless colored pencils, so I rubbed the shavings all over a piece of paper and then erased some swans into it. The brown is actually a mix of every color in the box.
It's not the best quality since my eraser was rather thick. What I wouldn't give to have had a kneaded eraser at the time.
