I strip off the bottom leaves from a salal stem (also commonly known as "Lemon Leaf) so I can have a longer stem.
This helps when I want some length down the cascade section of the bouquet.
Another long piece to the lower right of the bouquet.
I saw a hole in the top where I tucked another tri sprig of ruscus.
Always take a step back occassionaly, looking your design over and deciding where another green is needed.
Although I want a balanced look, I don't necessarily have to be symmetrical (making it look like a mirror image on both sides).
Keep checking the sides. You want to cover up the mechanics (the foam and the white cage) without over stuffing the greens.
If you look on the back, you'll see open slots where you can insert more greens. These are usually filled "good side out" - so that when you look under the bouquet you see the "good" face of the greens, making your bouquet beautiful from both back and front.
I'm finally satisfied with the overall look and have still left plenty of room for all the daisy stems I plan to insert.
If you wish, you can glue salal leaves to the underside of the bouquet holder, concealing the white bottom of the holder completely. Another choice is to create a salal leaf collar and add stems so that it looks like a hand-tied bouquet.
If you plan on this, it might be easier using the green Super Wet Bouquet holder which helps conceal the mechanics easier.
