Hi girls,
Yes my pattern came out at just about 8" and if you remember I extended past the paper (as the pattern barely fit on an A4 sheet) and then added the side, top and bottom panels.
Getting templates to print at the right size inside a tutorial is tricky and then you have to hope the person who prints it remembers to set No scaling or cancel Fit to page in their printers settings.
I have added some extra destructions to the stage of the tut ... thanks for making me aware of the problem.
