Now I continue adding more blades of grass, inserting them right next to each other in the foam.
Rotate the bouquet holder around, inserting the sharpened end of each blade of lily grass.
Placement doesn't have to be perfect. You can overlap the grass if necessary for good coverage.
I love using greenery in creative ways. The nice part is that just two or three bunches of grass is usually sufficient for bouquets, corsages, boutonnieres and other decor.
Now that I have all my grass inserted, I'm going to gather the ends lightly in my hand and pull down to tape to the neck of the bouquet holder.
