Anything invoking a feeling of love will be an appropriate wedding favour for a romantic wedding. One great example is a silver picture frame with the word love inscribed into the silver. This is a very simple favour but it is also one which accurately conveys the message of love. Your guests may choose to put a picture of you and your partner in the frame to serve as a definite reminder of you and your wedding or they can use the picture frame in any way they wish. However, if they decide to use the frame, it will likely always remind them of your wedding. Each time they see the frame displayed in their home, they will fondly remember how much fun they had at your wedding.
Coasters can also be given as favours for a romantic wedding. This may not seem like a particularly romantic gift because it is more of a practical item but you can find ways to make this simple gift more romantic in nature. For example coasters can be purchased in a heart shape or in a design which reflects the theme of love and romance. A coaster displaying a picture of a bride and a groom is one way to do this. The coasters can also simply have the word love written on them or can be decorated with heart shapes to make them seem more romantic. There are even heart shaped coasters available which are designed specifically for wine glasses. These coasters are much smaller than average coasters and can create a very attractive appearance.
Books can also be an excellent idea for wedding favours for a romantic wedding. Again, this may sound as though it will not be particularly romantic because books are typically viewed as being very practical items. However, your choice of book can greatly influence whether or not it is appropriate for a favour at a romantic wedding. A book such as a book of love poems or quotations related to love would be very appropriate to give as favours at a romantic wedding. With a little creativity you may also find other books which are appropriate. For example if you and your partner are particularly fond of a certain classical romance novel you might consider giving each of your guests a copy of this book.
