If you do not take this precaution, you will have water leaking all over the place. Place the foam into the container, and then using specialized florist tape, attach it in place to the top of the base. The overall shape of this design is roughly a half a sphere. If you think of the northern hemisphere of the earth you will have the idea. To establish that, we start with our snapdragon.
Snapdragons are a lovely flower, and come in a variety of colors.
The tall spikey shape enables us to form the general boundaries of this design. First we place a snapdragon into the center of the design. Next we place a few more along the baseline, working around in a circle. Notice that in covering our mechanics we have used spanish moss. This is placed very loosely so that we can continue to add stems of flowers.
