My mother designed and assembled the flowers for my wedding, so I needed to find a floral wholesaler that would sell to the public. Pikes Peak was easy to work with and saved us a significant amount of money. They had all sorts of floral supplies (ribbon, vases, tape, etc.). If you want a specific type of flower they will special order it for you, and they also have a good supply to choose from for fillers.
We decided to do our centerpieces ourselves. We ordered from Pike's Peak our vases and flowers. If you pay for it all on a Wednesday, you'll receive a 20% discount on certain items. The centerpieces turned out beautifully. We picked up some ribbon for pew bows and some bouquet jewelry from here. We were also able to meet up with our florist here to pick out what colors and types of flowers I wanted for the bridal party.
