Do not place in direct sunlight, this would cause the painting/drawing to bleach and lose its colour. Alternatively you could frame it behind UV protected glass.

Avoid placing in spots prone to humidity or fluctions in temperature for example above a radiator or heater or in a bathroom.

Periodically check your artworks for signs of damp, discolouration and distinctive brown marks (sometimes called foxing) are most likely to appear on the back of artworks initially. It's a good idea to remove pieces from the wall a couple of times a year to check everything is still shipshape.
