A flower garland that is meant for a table top is designed differently than a wedding garland that is draped over doors, windows, and outdoor gazebos. One is designed all around, with flowers on all sides, while the table design is flat on the side that will rest on the table surface.
For this design, you'll need:
First you'll need to green in the flat blocks of Oasis foam. Allow the garland foam to "float soak" - which means you place it face down in the water tube and allow it to draw up water naturally. If you try to force it under to make the process quicker, you can cause air pockets in the foam. These dry pockets means faster wilting for any flower stem unfortunate to be inserted in that area of the foam.
Fill in with bulk greens. Good choices are leather leaf, ming fern, salal tips and Christmas greens.
Filler flowers such a limonium, baby's breath and spray asters can help fill in a long garland.
Large headed flowers such as hydrangeas and Asiatic Lilies are gorgeous. If you were to try and create these without a water source, the hydrangeas and other water loving flowers would soon wilt.
Here the designer is inserting lush dendrobium orchids, which is absolutely stunning. But remember - exotic flowers will cost you a lot more in a design this long if packed with expensive flowers.
Adding in gold decorative wire adds a gleam of richness to any table flower garland. See how the design can now fall gracefully over the edge of the table since the netted garlands will allow this flexibility.
