I notice a lot of times when similar questions are asked. People don't usually respond. I think some people have or had a similiar ritual but are hesitant to give a lot information because the ritual is private and sacred to them. I think sometimes people look at it like this is what we did, it's special and it's ours and I'm not sharing.
I found a link that has different handfasting rituals on it that you may want to take a peek at:
