We did tendus to the front , to the side , to the back , and to the side again ; this was to prove typical of many exercises involving moving one leg ; the technical term for this sequence of directions is en croix : in [ the form of a ] cross . But you should know the cultural and historical background of your art , even if you are an amateur , and once you have been shown a step , it helps to have an additional description to which you can refer at home . I am also editing a GWG whitepaper entitled Workflow requirements for PDF / X documents , which will hopefully be published this Summer . In addition , it gave me such pleasure to do something that was so completely unlike me .
