I always use a flower sealant on every hand bouquet I create. Two good brands are Finishing Touch and Crowning Glory. Remember that a home refrigerator REMOVES humidity from the air. A florist cooler adds in humidity at the rate of 80% or higher. Those flower petals need moisture to keep them from early transparency.
Don't skimp. These products definitely extend the life of your precious wedding flowers.
Thoroughly mist the bouquet and allow to dry before storing in your refrigerator. If you are using spray roses, I urge you to arrange for refrigeration, since these variety of roses tend to blow open quickly.
Just make sure there is no fruit in the refrigerator and turn up a little warmer than usual. Don't store flowers in the very back, which tends to freeze if too cold.
You can see that creating unusual designs is not really that difficult - it's just a matter of paying attention to the fine details!
