Some top wire services such as FTD and Teleflora encourage their affiliates to offer "upgrades" to the customers. This generally results in a few stems - but is mostly additional "bigger and better" greenery.
I love adding myrtle because of the long lines and the pleasing scent when freshly cut.
Insert the slender stems the same way you would insert other flower stems.
One branch may have several laterals that you can cut apart, using the shorter ones low on the sides.
Don't forget to strip the leaves off the bottom so you are inserting a bare stem into the water vase.
The long graceful lines of myrtle draw the eye upward, making even short stemmed flowers seem longer.
Insert the additional myrtle from all sides, turning the vase every now and them in order to get an evenly designed vase that looks the same from all sides.
Don't forget the sides. Extending greenery out to the sides makes the vase seem bigger and better.
It doesn't really take much to add a lot more interest to this design. You can see how a mixture of different greenery really adds dimension and interest to the flower design.
Notice my water, despite all the flower stems and greenery added, is still clear and pristine without a single leaf marring the beauty of the clear vase. The crossed stems form a strong network of interlocking stems. Florists sometimes give their vases a spin around to see if the flowers all stay in place.
This is jokingly referred to as the "delivery man spin" - indicating that even a bumpy ride in the delivery van shouldn't dislodge a well designed vase of flowers.
The actual flower design is finished. Let's go on to the traditional addition of a red bow to the design.
