I've decided to use ivory calla lilies, dk. purple calla lilies, green cymbidium orchids, and ivory hydrangea for my bouquet and my MOH's bouquet (no bridesmaids). My idea for the centerpieces was to have tall, glass vases filled with water ro include one green cymbidium orchid stem (with about 8-10 blooms) submerged in water,1 transparent candle floating on top and crystals at the bottom to hold the flower down. HOWEVER, I've had to cut my floral budget in half and I LOVE LOVE LOVE the orchids. Would it be uncoof to use real flowers for the wedding party and silk flowers for the centerpieces?
