Are you planning on writing your own vows? 
Let me give you a couple of tips you can consider:  
1) Decide if you want to write them together or not. 
2) Read vow examples for inspiration.
3) Consider a structure that you both can use as a jumping off point. 
4) Decide on a word-count maximum. 
5) Focus on things that symbolizes your relationship.
