Although I was hoping to find silk flowers of the actual types used in Kate Middleton's bouquet (sweet William, lily-of-the-valley, myrtle & hyacinth) I had no such luck. So, I just bought some silk leaves and little white flowers and went with it. I adore how much meaning went into every detail of William and Kate's actual wedding though *sigh*, how perfect.
Anyways, I ended up with 2 stems each of 2 different white flowers and one stem of leaves. I already had some floral wire and tape on hand (though I didn't end up using the wire).
I cut the flower stems apart and started bundling them (not knowing how large I'd be making this bouquet) and taping them together.
Then I added some leaves, then more flowers and went back and forth arranging the stems while taping more into the bouquet.
About 10 minutes later, this is what I ended up with, which for costume purposes works just fine:
Here's the side view:
I bent a couple of the long stems around to make a handle for the bouquet and wrapped them in floral tape.
