Not having one exactly...well, not sure. Getting legally wed this year, then having the party (and maybe handfasting) a year and a day later. I'm quite into the idea (although I balk at certain aspects of paganism and would never call myself one per se, but it's perhaps as close as I can come to identifying with a religion) but DP not remotely that way, so would have to modify so it worked for both of us.
So just wanting to hear what your experiences of handfastings have been and whether there's any good ideas I can nick.
