Finishing boutonniere stems can be done in many ways. The simplest (and most traditional) is simply letting the florist tape wrap show. Other methods include ribbon wrap, adding pearls, or curling individual wrapped stems upward.
Paying attention to this kind of detailing gives your finished boutonnieres an edge and looks professional.
After wrapping the decorative wire completely down the boutonniere stem, I finish by shaping the wire into an open loop at the bottom.
Use something round or oval to wrap the wire around to get a nice, even shape. Here you can see I used the handle of my wire cutters.
Bend the wire up so that the cut end will be in the back of the boutonniere.
