Absolutely agree with everyone else,

Weddings are so stressful and to do your daughters would be 10 times the stress level.

As Mother of the Bride you should be spending the day being pampered and enjoying being with your daughter, not getting broken finger nails and rose thorns in your fingers, and hand that won't come clean.

I've been a proffesional florist for nearly 20 years and I would definately seek out the services of another florist to take this pressure away from me if it was my Daughter's Wedding.
