I found Project Wedding while reading through some message boards on some random site I was reading one day, and it has become my favorite place to discover potential wedding vendors. I think they are a Weddingbee sponsor as well, which may have been where I discovered the site.
Every single reception location in Seattle has received an email from me because of Project Wedding. The categories for Seattle include reception sites, bridal shops, photographers, makeup+hair, flower+decor, entertainment, and the list goes on and on.
A lot of the vendors have reviews, either posted directly onto the site by brides, or from knottie bios. (Although do beware of fake reviews posted by the vendors themselves, I am pretty sure I came across one of those).
It looks like the cities that have their own pages right now are San Francisco, LA, New York+Jersey, Chicago, Seattle, and Boston. They also have a nationwide page, and you can always use the search box to type in the name of your vendor and see if they have any reviews available.
Anyone else have any great resources they would like to share?
