Take care in handling ming fern. It has thorns that can be quite sharp and cause damage to your fingers.
I snip off some of the lower laterals of the ming fern and set them aside to use in corsage and boutonniere work.
Add the ming fern stem to the back of the calla lily bouquet.
Be careful not to overwhelm the bouquet with "too bushy" of a look with the ming. Remember that the greenery is to compliment the bouquet - not hide it or overwhelm it.
