Decoupage (from the French word for cut) is the craft of decorating household objects. It originated in the 18th century.
Decoupage is actually quite simple! If you can cut and paste, you already know most of the techniques involved. Basically, you cut out pictures; (most popular and handy is using printed tissues) , you glue the pictures onto an object; and then cover the object and pictures with a few coats of glue/decoupage medium to protect it.
Although you can buy supplies made specifically for decoupage, you can also use supplies that you probably have lying around the house. This makes decoupage one of the cheapest crafts around. This is because anything can be covered by decoupage such as wood, metal and ceramic.
Also your old tin, trays, vases, and old furniture can be given a new magic touch by decoupage.
