How to create this floral design

Drop the table deco in a bucket of water. It will float, and as it absorbs the water, it will sink. Do not forcibly submerge under the water. Allow it to saturate on its own.

Wrap the container with the button wire. Insert greens on each end, and out the top off-center.

Fill in with other holiday greenery.

Cut a gerbera and insert into the top center of the foam.

Add a second gerbera close to the first.

Cluster a third gerbera, creating a triangle of blooms.
