I'm going to add a little more texture and design interest with another great greenery - Israeli Ruscus. It has a little more broad and rounded leaves than the Italian Ruscus I have used in so many other tutorials.
You can cut apart the stems in separate single or two leaf parts, which still leaves plenty of stem for insertion into the bouquet foam.
Tuck a few leaves here or there, adding in a different shape leaf that adds a lot to the overall design.
A view from the side should show most of the foam covered. Don't think the greens have to be crammed in, just filled enough to cover the foam but leaving enough room for the daisy stems that you are going to insert.
