Amazing Paper Art made using just a sheet of A4 paper

Artist Peter Callesen cuts intricate patterns from a white sheet of paper and uses the cutout to fold breathtaking designs such as skeletons, insects and buildings.
The precision work transforms a piece of paper worth only a few pence into a piece of art that sells for £2,800.
Each model takes up to two weeks to sketch, cut and fold.
Peter, from Copenhagen, Denmark, likes to use A4 paper in his work because people use it widely in the home and office and can easily relate to it.
