Quilling

I had never heard of this art form until I watched an enjoyable interview with this remarkable young artist at the Hong Kong Tatler:

Here's more information from Wikipedia:

Quilling or paper filigree is an art form that involves the use of strips of paper that are rolled, shaped, and glued together to create decorative designs. The paper is rolled, looped, curled, twisted and otherwise manipulated to create shapes which make up designs to decorate greetings cards, pictures, boxes, eggs, and to make models, jewellery, mobiles etc. 

During the Renaissance, French and Italian nuns and monks used quilling to decorate book covers and religious items. The paper most commonly used was strips of paper trimmed from the gilded edges of books. These gilded paper strips were then rolled to create the quilled shapes...  In the 18th century, quilling became popular in Europe where gentle ladies of quality ("ladies of leisure") practiced the art.

The word "quill" as an avian appendage dates back to Middle English.  Presumably early artists used to wrap their paper strips around quills.
