So me and my fiancé are not having a wedding party at all...personal preference. I'm trying to figure out how to incorporate my 13 year old (female) cousin in our wedding because I am and always have been very close with her. I have one sister who will be doing a reading for us. I can't figure out how to include my cousin in a way that shows her I want her there and not pawning her off just to be a guest book attendant or something...she's also at that age where it's iffy to make her a flower girl because 1) she may feel awkward doing that and 2) my own sister has a hard time coming to terms with not being in my wedding and making my cousin my flower girl may make her feel (even more) un-included if I have one member in my wedding and it isn't her (my sister's feelings are important to me, so please don't write it off say something like "she can get over it").
ANY ideas on how to [better] include my sister / my cousin without doing a bridal party?
