[You know, I never even thought about a floral arrangement for the restrooms.] In each restroom, there will be a skinny cylinder vase with white hydrangeas, ivory spray roses, and hints of silver dollar eucalyptus and jasmine vine.
Hydrangea centerpiece as one of the three vases on the tables. I like how the other flowers are mixed in with the hydrangea. Maybe put them in mason jars if you want to go with a more country/rustic theme.
