When you are newly engaged, it's very easy to go from calm to overly excited and in a matter of seconds. More often that not, it's been my obversation that couples literally just don't know where to start.
Beyond the obvious narrowing down your Vendor categories, when it is time to actually participate in initial meetings, it's common place for selecting of a Vendor to become quite the daunting task. Here's my advice, instead of just focusing on what you DO like, cutting out pages and pages of every flower that gets you to smile, how about you narrow it down to your top 5/10 items that you like and also select 5 that you DO NOT like.
As a Vendor, it's just as easy for us to help guide you down the right path to wedded bliss knowing what you do not like (i.e. bright colors, floral patterns, the outdoors, children, etc.) as it is knowing what you do like. Weddings are about personalization. You want your day to be memorable and to ensure that we can translate your vision for the day, and letting us know what you don't like is just as important.
So, if you find yourself struggling to figure out all the right things to select, how about starting from the opposite end of the spectrum, literally. You'd be surprised. Sometimes you know more than you think!
