Weddingbee boards

So, my wedding has now been pushed back a year and a half from when we originally hoped to have it, and I've had a lot of time to think about what I hope our wedding to be like and then change my mind dramatically.  But as much as I have changed my mind on some things, FI won't change his mind on long rectangular tables for our reception.  He thinks they look elegant and match our venue well; I just think they inhibit good conversation and inclusiveness.  But whatever.  He gets his tables.  So I started thinking about what centerpieces would look good on them and considered all sorts of tall sprays of flowers and the like, but, like so many things in the wedding world, got sick of them after overexposure.  It's not that I don't think they're pretty--I really, really do, and if I were to book a florist or plan my floral arrangements (I haven't decided whether or not to DIY yet) RIGHT NOW, I might include them.  I don't know.  But I'm just wondering if anybody has used long, short (in height) rectangular centerpieces.  Something like this:

The image isn't quite what I had in mind, but the vases are about right.  I'd probably want them a little wider and the glass a little thicker, and I'd fill them with some water, ivy, and some floating flower heads (as if I'd just transported a late-spring pond to the middle of my table, that's what I'm envisioning), and I don't know what else, and surround them with candles of some sort.  Anybody used these vases?  Or come across images of weddings that did?  I'd love to see inspiration pics!!

Yay someone responded hahaha.  I needed the consolation!  I've got to admit, centerpieces are one of the things that excite me least about wedding planning.  Too many options; it's overwhelming!  I think that short centerpieces will make it easier for people to communicate across the rectangular tables, instead of confining the guests to talking to the people directly next to them, so thanks for bringing up shouting...+1 to the short centerpieces.

Good pic!  When I googled 'rectangular centerpieces', what came up was mostly tall rectangular vases like this: 

Not quite what I was looking for!!

I think rectangular tables are handsome, but I guess I just can't get past memories of being in grade school (and college...) and sitting in the cafeteria at the end of a long rectangular table, unable to hear or participate in the conversation going on. :( I mean, doesn't it suck to be seated at the end of a long table?
