yep just cross them try and puff them up a bit so it doesn't look flat, try and pin your stock pin fairly high and close to the "knot" it will help.
Hope this link works - this is what your aiming for
If its brand new it may have been starched? Do you have time to wash it before tomorrow? Try not to worry too much about it I doubt the judge will care what stock you have on! Good luck for tomorrow x
