When you make a corsage, don't waste anything of your flowers! The tight buds and unopened buds can add a lot of interest to your corsage design.
Apply glue to the stems and tuck in here and there in the open spots.
Allow the glue to set as with the other flowers.
Continue adding the smaller flower heads until you are satisfied with the design. Do not go overboard, as we still have to add the filler flowers (the wax flower and snapdragon florets).
Some gaps for the filler flowers should still be showing once the secondary flowers (carnations) are in place.
View your corsage from all sides to be sure there is not large open gaps.
