Pixieperfect - those centerpieces are stunning!
Our DOC, her assistant, and seven or eight friends/family members will be setting the arrangements up at 1:00pm for our 6:00pm ceremony.
The tricky part is the arrangements will be made the night before by myself, my maids, and my family using a ton of floral foam, tape, fixative, and pins. Then we will gently place them in boxes I've recycled from my job, stored
downstairs in our (hopefully) cool basement, and periodically misted with water from a squirt bottle.
They will be transported in a UHaul (the only vehicle we have large enough to transport all our DIY - crazy, I know!) to our venue and rewatered, remisted, etc. upon arrival to the venue. We will pack up a dozen or so extra roses and such
in a bucket to refresh any flowers that are unable to survive the trip.
The trick will be hydration, hydration, hydration and making sure the boxes are the right size for each arrangement to keep them from getting jiggled around too much in the truck.
This is probably the only thing I am stressed about, but I've done a few mock ups (including transporting them in my car) using flowers from my garden and so far, so good.
