Choose the vase or container for your oval arrangement. The size of your container is a defining factor in defining the shape and final result of your floral arrangement. Pick a vase wide and deep enough to hide your floral foam.
Select a variety of flowers and greenery in proportion with the scale of your vase. A good floral arrangement must have the right physical weight to stay in place, while also having visual weight and balance.
Secure the floral foam at the bottom of your container. Cut the ends of the stems if you are using fresh flowers.
Frame the outer edges of your arrangement to create the basic oval shape. Use lighter flowers and the greenery for the edge.
Create a focal point in the center of your floral arrangement with the largest or brightest of your selected flowers. Fill in any spaces to your preference, using filler flowers and greenery.
Decide on any accent pieces you want to include. If your arrangement is for a specific event, incorporate the theme with your non-floral accent. Be sure to use your accents sparingly so the focus remains on your flowers.
