I know that this is a bit too late for your party... but maybe you can use it at another gathering it is smething I wrote for my blood sisters and my sisters by another mother.... my friends~

Sisters:
I am light hearted and strong
I am sensitive, demanding and kind
Intelligent, nurturing, and life giving
I am wild and wonderful, fancy and free
I am a barrier of fruit, I lead with my heart
I am a child, innocent, uncorrupted and week
I am the worrier, defense, prosecution and judge
I feed the masses with my hunger and love of life
I am the poet, the prophet, the laughter, the tears
I am the subject of sonnets and love songs
I am magic, spell binding and crafty
I am all the caricatures in the play
Mother, Aunt, Grandmother,
wife and Friend~
