So it's completely upto you how you'd like your venue (ceremony and reception) to look. So if it's not naturally everything you have wanted it to look like, there are things you can do about it!
You can hire a room dresser, who will work with you to create the look you want. This could include the use of chair covers, candelabras, mirror plates, fish bowls, fairy lit bay trees, aisle carpets, drapes, fairy kit back drops, thrones... You get the idea.
Now, a lot of these items are not too expensive to buy yourself so I'd recommend getting a quote from a professional, then work out how much it would be to buy. Your venue should be able to offer you contact details of the nearest room dresser.
Now, I've recently found a great website which is great for anyone who wants to add a bit more glamour to their venue. It's www.wedding-bitsnbobs.co.uk They have a great range of chair covers, gifts for the guests, gifts for the happy couple, postboxes,hen do' items, favour boxes...just check it out yourself. Whether your the bride or a guest, I'm sure you'll find something to buy!
Any questions, just ask!
Hope this helps.
