I'm going to add in an inexpensive greenery to surround the flower heads. Leather leaf fern is a standard product at every flower shop and is very reasonably priced. Leather leaf is packed by weight, with generally 15 - 20 stems in a bunch. When you order, be sure to check amount of stems per bunch, as my tutorials are by needed stems . . . not needed bunches.
You can usually remove the bottom two to four lateral branches and set them aside to use in boutonnieres, corsages or centerpieces. The tip portion is what you need to create a foliage collar around this hand tied bridal bouquet.
Here I am removing the bottom leaves.
You can see that only the top portion of the leather leaf is what is going to be place against the base of the flower heads.
Face the "right side" of the leaf upwards and place it against the stems of the bouquet.
Tape it into place with floral tape, making sure it is tightly bound.
Don't forget to inspect your bouquet and snip off any broken or bruised stems. You can set these aside and place in water for use in corsage or boutonniere work if the bloom still looks good.
