Did YOU, or do you know anyone, who made their own wedding bouquets?

I am a frugal bride. I am planning (or at least WAS) to make my own centerpieces and bouquets. My FMIL (who is not financially contributing to the wedding <—that bit is significant b/c I wonder how it impacts how far I should consider her opinions) keeps mentioning that I need to secure a florist for our bouquets (the wedding is in Nov 10) She knows that I was planning on a DIY situation, yet continues to insist I need a florist, to at least arrange the bouquets. My original idea was to have the bridesmaids hold 4 large hydrangea stems wrapped in ribbon (when I came up with the idea I premade one, and loved the look), and myself a bouquet of ivory hydrangeas and ivory roses. Simple enough right? 1. Does she know best because shes been a bride, and has a daughter whose wedding she helped coordinate, or 2. Should I go my route and save hundreds doing them myself, buying floweres thru a close friend who is a wholesale floral supplier (NOT florist, as she does not make arrangements but rather distributes the flowers to wholesale clubs etc.) help!

Definitely do it yourself! Since you have already made them, you know what you are doing and how it will look. I think your idea is really pretty. I made my own. My bridesmaids each had three lilies and three roses with some foliage and I had a dozen roses and three lilies with foliage. I wrapped each one with ribbon and they looked nice. I also made orchid and rose corsages for my mom, his mom, and his two grandmothers. Those were all real flowers. We were on a budget, so the centerpieces were artificial, but I did them too. Each of our parents tables had a larger arrangement of artificial ones and our moms still display them. Since you have the knowledge, skills, and necessary items available, go for it!

EDIT: If you have to, point out other things that you are doing yourself and reassure her that you are not just ignoring her. This may backfire if she says you are doing too much, but a schedule can convince her that this will be done at this time, and that will be done at that time.

I would second Reba that the corsages are difficult. In my experience, they were harder than the bouquets, but still doable and well made.
