I personally went for flowers, but the pics of peary bouquets look lovely too.
Mel & Mike, how big is the bouquet? Its hard to tell, but the actual beaded area looks very small. I'd want to make sure it wasnt a mini-size, as that would look odd. If it was the size of a normal, floral bouquet, & it fits your theme, then why not be a little different? At least it will never die!
