Here is an easy idea of the delightful floral object which can be adapted again and again using a minimum of materials but extremely effective. The mechanics are very simple, the construction is light and stable, the design unique and will take attention to any place.

Suggested materials:

Calla Lilies
Mini Oncidium Orchids
Lily Grass
Angel Seeds or seed pods of Oroxylum Indicum
Rafia
Hot glue
Midollino Sticks
Galvanized Wire 12 gauge
Masking tape
Plastic water tubes
Rafia
Tools
A stand
A styrofoam disc or sheet

Process:

Start with cutting the styrofoam. I did not have the disc, so I cut half of the circle of a styrofoam sheet.
Trim the edge of the circle to make it smooth. The shape of the bottom part reminds a boat. Cover the base with some masking tape. The masking tape will prevent a melting process of the styrofoam while you use the hot glue.

Glue the Angel Seeds onto the surface of the base with the hot glue. Alternatively, you can use small pieces of bark, cork, decorative Washi paper, Lunaria for the same fluffy effect.

For the foot of the art piece I used an Ikea Christmas ornaments stand, I just carefully bend an axis it to one side.

Align the base with the foot, mark where is going to be a hole at the bottom of the styrofoam base. Push the standing axis into the styrofoam to make the hole, then secure those two pieces together with the hot glue.

Next step is to create a transparent part of the art piece. Cover the galvanize wire with the floral tape, then wrap the wire with the rafia, add the wire pieces to the base completing the full circle. Also, add the midollino sticks. It is a good idea to secure all parts with the glue to prevent wobbling. Cover water tubes with floral tape and then with rafia. Put the tubes onto the base planning how the flowers will be inserted. Fill the tubes with water.

Place the botanical materials inside the made Moon form, bending calla lilies, orchids, and weaving lily grass between the midollino and wire.
