Grasses can add a lot of interest to arrangements. The stems are slender, however, and you have to use care in inserting them into the foam by first piercing the polyfilm on the Oasis spray bar.
I usually use floral tape to bind several blades of the grasses together and insert them as a group into the foam.
You can create loops or let the grasses flow over the arrangement is graceful sweeps.
I added more salal into the arrangement as I move up on the sides.
I could continue greening the entire bar or insert the flowers in between the greenery.
