"Just because you can't see something，that doesn't mean it's not there." This old saying is quite meaningful for British sculptor （雕刻家） Willard.The items he creates are so small that most of them fit on the bead of a pin.You can see them clearly only through a microscope （顯微鏡）.
    Many people want to own his art pieces.He's been honored by the Queen of England for his great art achievements.At every one of his exhibitions，the question is always the same.How does he do it？
    The answer is very，very carefully.So carefully，in fact，that he actually slows his breathing down and works in between breaths.Willard usually works under a microscope using special tools that he creates.To paint his works，he uses the hair from a fly as a paintbrush.
    Creating these detailed works is a very long and difficult process，and it isn't always enjoyable. "It is a terrible dream when I start but a nice dream when I finish，" he says.A single item can take at least several weeks to complete.
    People have asked Willard why he chose to do something that needed effort and took time.His interest in creating small things began when he was five.He started creating houses and playgrounds for ants.Willard was not a strong student.He had difficulty in reading and spelling words.Some kids used to call him a loser.This made him feel small，so focusing on little things helped him to feel big.The smaller his work got，the bigger he felt.A newspaper reporter said， "Willard has shown the world that he is special.Though his works are small，he's great."
