My bouquet is solid standard roses. I want to be sure that the mechanics of my design (such as the cage and the florist foam) are completely concealed.
I'm going to use wispy tree fern for this purpose. It is inexpensive and a few stems covers a lot.
Cut individual fronds off the main stem of the tree fern. Insert these individual stems into the wet florist foam.
Fill in over the whole surface of the foam head.
Tree fern lends a light feel and look that compliments the tulle well.
Fill in until you have a high mounded look.
