A knitted cover and a method of forming a two dimensional knitting pattern for the cover .

These edges are broken down into courses or rows of progressively ranging lengths, and the courses or rows are rearranged to form new edges in which a particular cours e or row is not necessarily adjacent its original neighbour before rearrangeme nt.
