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. The traditional technique used 30-40 layers of varnish which were then sanded to a polished finish. This was known in 18th century England as The Art of Japanning after its presumed origins.
There are many varieties on the traditional technique involving purpose made 'glue' requiring fewer layers (often 5 or 20, depending on the amount of paper involved). Cutouts are also applied under glass or raised to give a three dimensional appearance according to the desire of the decouper. Currently decoupage is a popular handicraft.
