Handfasting

I brought up the idea of becoming hand-fasted to my boyfriend of two and a half years and he loved the idea, so did his roommate. So now not only am I trying to figure out what to do for my handfasting I am trying to help another couple plan their hand-fasting. At this point I would like to inform you that I have never done one before nor do i have an exact idea of what to do. Everything I can find is for a permanent ceremony and we both want the traditional year and a day ceremony as a practice run for marriage. This may be harder than what I initially thought.
