This red rose wedding bouquet is ready to use at this point. But . . . you can choose to add in different varieties of secondary flowers, use a filler flowers (such a Baby's Breath) or simply fill in any signs of mechanics that still shows with more greenery.
As you can see from the side, the overall bouquet has a nice domed shape and is not flattened.
This traditional bouquet can be created in the same manner substituting calla lilies, Gerbera daisies, carnations and more. The look would be totally different . . . but the design technique would be the same.
I did fill in a few gaps where the bouquet holder showed through the greenery. The bouquet is completely done with designing at this point if this is the look the bride desires. I am going to take it a step further, however, and show what the same design looks like with a bit of filler flower.
