Hi there - couple of suggestions - put a few sprigs of lavender or cloves into each bag or i would imagine that only one or at most two bounce sheets per bag / suitcase would be enough (top and bottom) if they are sealed . If the clothes are hanging on a rail , my mother used to get a small orange and pierce it all over with loads of cloves and hang it on a ribbon among the clothes. If you are concerned about the chance of marks/ stains from the lavender / cloves you can just put it in a fine cotton bag.
