American artist Lisa Nilsson creates anatomical cross sections of the human body using rolled strips of paper, a technique known as quilling or paper filigree. Quilling is a time consuming process in which paper is wound tightly into small rolls of different colors and then positioned to become works of art. Nilsson is able to choose exactly the right material to imitate the organic structures making each piece appear as real cross-sections of humans and animals.
The construction is done with Japanese paper and the gilded edges of old books. Quilling was first practiced by Renaissance nuns and monks who made artistic use of the gilded edges of worn out bibles, and later by 18th century ladies who made artistic use of lots of free time.
