Brides are often asking the question "how can I improve my venue" or disguise the decor?
Wedding draper are a brilliant way to do just that. This is a picture from http://www.weddingdecor.com/backdrops.htm they do some stunning and striking wedding decorations using drapes.
Although these are spectacular if you don't want to go to this extent you can use the idea as much or as little as you like to achieve great results.
One piece of advice from me would be if possible try and get all this finished the night before so that you can check it and not worry that your venue won't be completed before the arrival of your guests.
