I was thinking it would be really special to have each guest bring a single flower to put in a big vase on the head table, or the guestbook table of the reception. I have already sent out my invites so I was thinking I would send out a little map to the ceremony as well as this request to the people that RSVP. But is this acceptable? People are coming in from all over the country, getting hotels, btinging gifts, etc...is it too much to ask them to bring a flower? is it weird to send out the request that way?
