Well if you are going to do a unity candle, it would be great for your children to all help light your candle and if your future husband has any for them to do the same thing, and then the two of you take your candles and light the middle one signifing that these are two separate families that are being unity. Instead of doing traditional vows you and your future husband could create your own. That would make it very special to say what is from your heart and how you feel about each other. Congratulations on your upcoming wedding.
