Cobweb painting
Cobweb painting, sometimes known as gossamer painting, is the delicate process of painting on canvases made from caterpillar and spider webs that have been collected, layered, cleaned, and framed. The fragile works of art on thin, translucent surfaces was practiced primarily in South Tyrol in the 18th and early 19th centuries. Fewer than 100 cobweb paintings are known to exist, many of which are housed in collections.
