To make the carrot petals, peel the carrot with a vegetable peeler and cut off ends. Use a sharp paring knife to mark the petals on the carrot by making 4 slits on the bottom of the carrot. Carve a horizontal line down the first slit. Repeat with a second horizontal line about 2mm away. Hollow out the carrot between the 2 horizontal lines to complete the petal. Repeat with the other petals and when you're done, you'll see the flower shape. When slicing the carrot, each slice will have a nice flower shape.
