If you're interested in writing your own vows, it's because you want something personal - words that describe you and your partner, and only the two of you. The only way that I can assist you in making that happen is by talking to you.
Whether you live far away and we meet via Skype, or you live around the corner and we grab a coffee/tea/beverage of choice, the first step of this process is to chat. I'll ask you questions about your relationship, but I'm also trying to get to know you: the words you use frequently, your sense of humor, the facial expressions that you make when talking about your partner. We'll go over the basics, like what sort of tone you're looking for and how long you'd like your vows to be. I'll ask you to come prepared with some sort of draft, be it a few sentences jotted on a napkin ten minutes beforehand or a full-on set of vows.
I'll take what you have and make it into what you want it to be. After our first meeting, I will send you a revised version of your vows and ask you for your feedback. Editing is an inexact science: there is no set number of exchanges that you will be limited to. We will work on your vows until they are just the way you want them to be.
Because this may take some time, I strongly recommend starting this process at least six weeks before your ceremony date. If you want a rush job, I may be able to accommodate your request (depending on my schedule) for a slightly higher fee.
