Hi,
First thanks for the replies and Paul the template. In the end I have created a template that splits the A3 into eight cells by declaring two rows and four columns. The "zine" she wants to produce is only printed on one side of the A3 sheet as the sheet is first folded in half along the longest crease leaving the eight zine pages on the outside of the fold. Next it is folded in half and then half again with the creases made in both directions. Open the sheet out and make a single cut from the middle of the long crease exactly one page width in both directions or a cut that is half the length of the page centred on the page. Next remake the long fold and hold the sheet at the left are right edges and slowly bring your hands and the sheet together so that the crease in the middle facing you comes toward you and the crease on the other side creases away from you. Keep moving your hands together until you form a cross when viewed from above. Lastly form the booklet by moving each arm of the cross into your left hand. Its harder to describe than do.
best wishes
Simon
