Metallic wire comes in a lot of different colors so you can coordinate them with your own wedding scheme. This wire also comes in copper, gold and silver (not shown in picture).
Here I'm going to use strong pink instead of green floral tape. There will be no need to hide the mechanics of this boutonniere design, since the colored wire is part of the look.
I wrap the wire around the stem tightly to hold the fold in place. Now I can let go of the leaf.
I'm going to cut this wire off and secure in the back.
Make a clean cut with a pair of sharp wire cutters. Do not use scissors. That is a good way to ruin your scissors!
Curl the rough ends tightly wire wire cutters and loop inward, burying the sharp ends into the leaf itself with needle nose pliers.
Press the calla lily against the folded leaf, fitting the head into the pocket formed by the leaf.
Using more metallic wire, wrap it around both the stem of the calla and where the leaf is folded.
Wrap several times, creating a tight bind and a touch of color as part of the design element.
Finishing off the back of the boutonniere neatly, with the wires twisted together and coiled so the cut ends point into the leaf.
The finished look should have the calla head with the tip just fitting over the top of the folded aspidistra leaf.
The bottom of the aspidistra leaf can be cut with scissors into a sharp angle that falls just below the cut end of the calla. It is good to either keep a water tube on the calla or stand the boutonniere up in a shallow glass of water until needed. (You might leave the calla stem a little longer and cut on the day of the wedding).
The finished calla lily boutonniere is sleek and polished, ready to pin to the wearer's left lapel.
