That is an idea how to decorate a prefabricated wooden box. As an idea for image I took paintings of Hunderwasser - a famous Austrian painter. He used to decorate houses in his hometown and they really looked great! Later the ideas of his paintings were used in a fashion industry to decorate scarves, gloves, home utilities and other stuff. You can find his paintings at http://www.google.ru/search?q=hundertwasser&hl=ru&newwindow=1&pwst=1&rlz=1C1SVEE_enRU411RU411&prmd=imvns&tbm=isch&tbo=u&source=univ&sa=X&ei=3n7wToj6FoGTsAbgzoUN&ved=0CDIQsAQ&biw=1366&bih=667 and may take wichever you like. When you paint a wooden box with gouashes you should cover your box with non-water varnish. Please, bear in mind that a water varnish will dissolve your painting because gouache can easily be washed away with water.
