Many of our items can simply be dropped into a vase. In some circumstances though, you might want to secure individual items in the container in specific positions. Stones and standard floral foam are good options, but spray foam might be one the best choices. When the material comes out of the can it has all the strength of whipped cream. Once it cures though, it is a strong and rubbery foam that grips items tight, and is very forgiving and resilient if you are the type of person that keeps on rearranging.

After curing overnight, the floral foam is stiff and ready to go.
