Let's break it down into circular tables and feasting/trestle tables firstly!
Go big or go home? Tree's, tall glass vases or boxed stands create that WOW factor! However tall arrangements aren't for everyone, low arrangements can be as awesome. Gold Hoop stands are popular with hanging glass baubles, Lanterns (we have a large collection) and glass cylinder vases (with floating candles or pillar candles) these can be teamed with flowers around the base, arranged in a ring or bud vases. Bowl arrangements with blousy blooms are always a nice statement.
Many floral pieces work well with the long tables. For impact go big with large glass vases or gold boxed stands, sporadically placed. Couples tend to go for the taller arrangements so that their guests can see each other and so that the tables aren't over crowded when the sharing platters of food come out. Foliage runners are also good for this reason, it gives a real relaxed and minimal look.
Bud Vases, Tea Lights, Taper Candles and Cylinder Vases are always a good shout for a romantic, low key vibe
Depending on if you're going traditional with a long table for parents, best men, maid of honour etc or Oval/Circular which is getting popular for the more relaxed couple or perhaps a sweet heart table, works well if you have family dynamic's or you just want to soak up the day just the two of you.
For a long Top Table, Long and Low table arrangements are traditional (this can also be used for the ceremony table first) this would usually be long enough to sit in front of you both.
A foliage runner with tea lights, taper candles and bud vases are sweet and romantic. A full and luxury foliage and floral runner which can drape down and puddle on the floor makes a massive impact.
Hope we've given you a few ideas!
