Nothing surpasses the impression of pulling them off correctly if you can withstand a little of hard effort ahead of time to learn them word for word. Making your vows in memory provides a more poetic experience in the moment than fumbling over your words on the spot. It is also a good idea to write out your own personal vows instead of relying on memory because you have more time to think about what you want to say and not be rushed into making a decision. Writing out your own vows gives you the opportunity to express yourself in a way that only you can. Your guests will appreciate hearing from you directly instead of through a minister or friend who may not fully understand you. Memorizing your vows also allows you to focus solely on performing them without worrying about mispronouncing any names or forgetting an important detail. The main advantage of writing out your own vows is that you have time to think of something special or meaningful for each line. This is especially helpful if you are looking for something poetic to say to your spouse. You can also add in some humor here and there if needed. It is recommended to write out your wedding vows at least six months before your wedding day so that you have enough time to practice saying them smoothly. Remember, though, to come up with something simple yet meaningful so that you don't wear out your nerves during your wedding ceremony.
