The biggest design I think I've ever done was a silk wedding bouquet{ugh} many years ago, I'm 5ft tall, and I suppose it was nearly as big as me. The most outrageous was a hand fasting wedding I designed. The bride carried a caged bouquet, the groom wore a suit of armour and a headdress of berries etc!! again, that was quite a long time ago. It was outragous but if you're into that kinda thing,it looked good.
