To decide whether or not you would like to use real or silk flowers, it may help you a bit to do a little bit of shopping around. It can be quite easy to head into just about any flower shop and pick all sorts of gorgeous flowers for your wedding. However, when you take silk flowers into account, you are going to have to do a bit of searching to find the quality that you are looking for. The last thing that you would want to do is cut corners on price and then end up with silk flowers that are less than desirable.
Why not go with the option of using both silk and real flowers if you find yourself unable to make a decision. Many brides have been going with the idea of mixing it up a bit so that they can have both real and silk without spending way too much money. Perhaps you could have beautiful silk arrangements for your centerpiece and then opt for real rose petals to be sprinkled on the tabletops!
