We did our own centerpieces, but I needed someone to do all the bouquets, corsages, and boutonnieres. I went to Pam, and she was great to work with, and they came out great, and went perfectly with everyone's outfits. These were delivered on-time, and delivery was only $15 extra.
Pam was really flexible when I came in 6 weeks before our wedding saying that I wanted just the bouquets, corsages, and boutonnieres. She had great ideas, changed the flowers to work in the budget, worked with my atypical color requests, and made some beauttiful bouquets.
She does a lot of full weddings with lots of flowers, and for that you probably have to book her early. I bet she would do a great job, but I didn't get into that part.
