Planning a wedding or special event can be nerve wracking. There are lots of details to handle.
My best advice is to do what you do best- and delegate what you don’t do well or are not attached to doing.
If you are crafty, then think of what you can make. Maybe your invitations are your artistic gift- and you have a very particular vision in mind.
Maybe it’s the flowers; or the cake. You may even be lucky and have friends or relatives that might give you your cake as their “wedding gift”.
Bring in a professional for the heavy lifting. Coordinating many of the vendors and their work, in my opinion, is “heavy lifting”. Completing a detail like what the flowers look like is only the partial job- where the flowers will be placed, which ones go to the church or the reception, when will they be delivered, etc.- are just a few of the rest of the details that have to be handled.
So, if that is not what you want to do- hire a professional. You will have less stress and more time to enjoy this very special time. And that is the whole point of the day- creating a memory.
