DIY Does NOT Mean Easy
I always say you can DIY anything, just not everything. Flowers are something that I am very hesitant to encourage brides to do themselves for a few major reasons.
You must do a test run! This is non-negotiable! Give yourself the opportunity to try floral arranging a few months ahead of time and determine if it’s really something you feel you can tackle the week of your wedding. You might find that you love it, and making centerpieces is calming! You might also find that it’s not your thing and doing 20 centerpieces and ten bouquets two days before your wedding is more stress than it’s worth. Either way, you’ll feel good about your decision!
Flowers are perishable. IE. You can’t do them more than a day or two ahead of time. So on top of your family coming into town, last minute appointments, rehearsal and rehearsal dinner, etc. you’ve got to find time to arrange flowers.
You have to buy much more than just blooms. In pretty much every wedding, we use pins, ribbons, shears, floral tape, wire, foam, vases, etc. It’s not that these things are complicated or challenging to track down, but these things can add up if you have to buy everything at once!
