Denim And Diamonds Party

I need ideas and websites for a denim and diamonds party. This is a great theme but I can`t seem to find much on it. I need to have some sort of themed favor that I can give to the girls that I host parties for and I`m on a limited budget(about $7.00 per person and I have 9 people including myself) to spend on favors, decorations, tableware. So, as you can see I have to be frugal and creative but I love to sew and do crafts so I can do a lot myself I just need help thinking about what to do.
Thanks for your ideas and keep them coming!
