Light 2 tapered candles, or use whatever candles you have handy. Isn't that what wedding is meant to bea single unit stronger than the total of its parts?
in the wedding rite, the bride and bridegroom light the center unity candle with the 2 tapers, making the stronger flame as representative of the stronger unity gained through wedding. If each partner has children, the youngsters may light the unity candles. If you carry a hand-tied bouquet, incorporate a white taper into the bouquet, and carry the taper up the aisle. These are some techniques that brides include monograms. Many brides find they can "roll their own" employing a readily-available application like MS Word or PowerPoint. If you are a graphical designer or have access to top of the range tools, you'd likely like Adobe Illustrator, but Word or PowerPoint are also fine. Nor have you got to restrict yourself to naked candles.
