If you want only a hydrangea and rose bouquet, this one is just about complete.
I have inserted roses across the complete design and it is ready to carry down the aisle. If you wish, you can add filler flowers like spray roses.
I have, however, left large areas open to insert flowers such as Gerbera daisies.
Two light pink daisies are clustered together at the top right.
You can see them better in this right side view.
You can add more color contrast by inserting darker pink Gerbera daisies in the lower left. This bouquet can be a finished design. If you want even more pop . . . add the novelty of green flat fern around the circumference of the bouquet.
