It has a plastic bottom, that can be hot glued to something or just used as is.
IGLUs are available in most craft or floral shops.
If using the longer pieces, insert all the way through the foam and up to the top, using two pieces in this way, the gazebo can be formed. Insert sprigs of transitional material such as caspia on top of the greenery, then place the short-stemmed flowers as a focal point, adding two dainty ribbon bows, if desired. A pretty one can be created by painting a clay pot with acrylic enamel paints from the craft store in the desired pattern, such as the one pictured. After the paint has dried, spray inside and out with a clear acrylic sealer. The gazebo will stay in place held by the weight of the soaked floral foam in the Iglu.
