Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from purpose-manufactured papers.
Each layer is sealed with varnishes (often multiple coats) until the "stuck on" appearance disappears and the result looks like painting or inlay work.
From Siberia, the practice came to China, and by the 12th century, cut out paper was being used to decorate lanterns, windows, boxes and other objects.
They combined decoupage with other decorative techniques already popular in Florence, such as gilt with gold leaf and carved wood designs.
As society became more secular in the early 20th century, and non–Roman Catholic tourists began buying more crafts from Florentine artisans, decoupage images became less religious in orientation and more reflective of famous Italian artworks in general.
