DIY Dilemma.

As the 6 month countdown begins, I am realizing it's finally time to get started with some of the DIY projects. Among the possible projects I will be tackling with one or two lovely BMs are the bridal bouquet and bridesmaids bouquets. I have been researching all the wedding websites and blogs and I think it looks doable (DIY-able?). Question: Do you have to be McGyver to do your own wedding flowers?
