.: Rustic Box Centrepieces

What sort of arrangements work well on the ceremony and/or top table, and which sorts of containers work well as centrepieces on long rectangular tables? When the flowers need to be long and low to suit a rectangular table and not obliterate people's view it really works well to have the flowers in a rustic wooden box. I think these look amazing in a more informal venue such as a barn where they tie in with the timber structure. They also work really well in a country marquee setting where a more relaxed look is sought. They make a lovely alternative to the conventional low arrangement in floral foam and as an added bonus make really nice giveaways afterwards!
