Decoupage

i decided to look at decoupage to see if i can use the technique to over lap different foils or relfective materials that have been recycled into making this. i though i would look at this becuase i have never done anything like, this before and im sure i can come out with nice outcomes. also because it is easy to use recycled materials as it doesnt have to be neat.

what is Decoupage?
Decoupage is artistic sleight of hand. What appears to be a painted design is actually paper, glued in place. What looks like lacquer is just a few coats of clear varnish, and what begins as an unremarkable piece of furniture becomes a bold, modern design statement.

if i was to use this on my bilboard i would have to use a thing called 'mod podge' for out doors, which is a strong lacquer.  i would use this so that it would completely seal any recycled materials i have on my bilboard, so that when it rains or when we get harsh weather conditions it will last and be waterproof.
