Use flexible, non-corrosive florist's wire to keep flowers in place in a vase . Place some inside the vase and then wrap some around the outside of the vase.
Stones, frosted marbles, and sea glass can also act as a frog in a vase. To add an extra touch, insert tiny waterproof lights. They last about 18 hours in water. Place them under the stones to light up the stones
Wrap curly willow wire around your hand and insert it into a round bowl vase. Add a few flowers. The willow wire will keep the flowers in place. Change the water every two to three days
