I'm kind of laid back when dealing with vendors. We did our homework, picked people we loved who had great reviews and I trust they know all the details of the wedding and will show up on time. That said, I haven't talked to many of them since the summer.
Did you (or are you going to) touch base with your vendors before the wedding just to make sure everyone is on the same page? If so, how far in advance is appropriate? Or should I just know that everything is set and not worry about it?
