I did mine with flowers from Fifty Flowers. There are also good options through Sam's Club and Costco, among others. Make sure you have a good pair of garden shears to cut stems. You'll also need floral wire and floral tape. I searched through their website and Pinterest for inspiration. I had practiced many times over the last 9 months or so with flowers from Trader Joe's. I only had to make my bouquet and 2 bridesmaids bouquets but it was still time consuming and stressful. Make sure that you have someone that will help and transport the flowers for you. I loved the way my flowers turned out and I know I saved some money by doing them myself.
FIFTYFLOWERS.COM!!!! They are amazing wholesale live floral and they give you instructions, “get the look” ideas and tell you everything you need to know from storage and best delivery dates to select etc. They gave amazing reviews with photos. I’d highly suggest them. They even do prearranged. Best thing I’ve found thus far.
