PS-Serrated edges were made by removing about half an inch of weft or weave depending on the direction of the fabric on each panel,to see how this works take a piece of Irish linen,cut it into a small square,now tear off one edge so that one edge is frayed away,continue the other side,that is exactly the effect we are aiming at with our model,dont worry too much at this stage as there is still plenty of time to think about jobs like this.
