Carefully unwrap your canvas, AVOID contact with sharp objects.
Keep your art away from water. The water will destroy the integrity of the paint.Keep from direct sunlight or heat. Over time, the sun's exposure will fade the art.
Use only a cotton cloth to dust (no water).
If moving or transporting, make sure both sides are well protected.
Do not rest anything against the canvas. It will stretch and take the form of the object.
