If you look closely at the photos, you'll see a few elements that make Betsy's wedding unique. 

There is an embroidered handkerchief tucked in the bouquet.

The toss bouquet is a smaller version of Betsy's bouquet
Also, you can see that Betsy and Marc's flowers are white while the rest of the flowers in the wedding party were made with cream-colored flowers.  I wrapped Betsy's stemmed bouquet holder in sheer white ribbon.

The bouquets featured roses (either white or cream-colored and pink), as well as lillies in beautiful deep burgundy, cream or white. Pearl sprays could be found throughout, remniscent of the Kummerer wedding featured on this site.  The holders were artfully wrapped with material taken from the bridesmaid dresses, a touch added by the creative Bride's family.

Two ring bearers, Mothers, Fathers, and special attendants wore flowers (not all shown).
