Here are some photos when I played Martha Stewart for a good friend's son and his bride. (See "What Is It About Weddings?").
Here I am with the bride, pointing out the crystal heart bead I put into her bouquet that corresponded to one in the groom's boutonniere. Her bouquet was made with hydrangeas, roses, peonies, stefanotis and lemon leaves.
I made the groom, best man and family of the bride and groom's boutonnieres from roses and gave the groomsmen thistles, which perfectly matched the color scheme. I decided on the thistles hurriedly as I went through the flower market the day before and the mother of the bride -- who wanted final approval on all decisions -- sounded a little doubtful when I told her about them on the telephone. By that time, there was no time to change our minds, so I assured her she was going to love the look.
Next day when I pinned a thistle on the first groomsman he was kind of steeling himself to wear a flower. You would have thought that he was going to be giving blood instead of getting a boutonniere pinned on him. When he opened his eyes and saw the "flower," he looked surprised and said, "Hey, what's that?" I told him it was a thistle, and he puffed up like a rooster and strutted away, all proud of his boutonniere.
Then, when I pinned the roses on the brothers and best man, they asked why they got roses instead of thistles and I explained it was because they were family (and did not explain that it was what the mother of the bride insisted on). They seemed to feel like they'd been shortchanged rather than honored.
Note to self: make boutonnieres out of the manliest "flower" you can find!
