Thanks SwingBeep for the picture and the details on the length of ribbon required :D
To tell you the truth I was thinking about the dangers of me accidentally wrecking a gondola with my powder ribbon tied to my ski (I know there have been lots of serious accidents caused by anorak tie strings in agricultural PTO shafts) and I've decided to take them off the skis and put them in my pocket before putting the skis in a gondola. I was thinking about using a dog clip or something to make it easier to get them on and off.
