We did a model shoot a while back where the model wanted to appear with lots of rose petals. We had a couple of thousand but could have done more. The biggest challenge though was fixing the petals. We should have got some toupe-tape in but had forgotten to do so. We resorted to sellotape which worked fine but judging by the shout we heard from outside the room, the model forgot this when it was time to remove the petals. Ouch.
