I have just started planning my wedding and am trying to figure out alternative roles for my best college girlfriends. Rather than having 7 or more bridesmaids, I have decided to just keep it at 4 with 3 family members and my very best friend since I was little. I still want my good friends from college to be part of my big day though. I want them to be more involved than doing a reading or handing out programs. Has anyone had or heard of additional roles other than bride's maids? Something where they can be involved in the day activities and mentioned on the program as well? Something like they are the "best girls" or "best of them" or something along those lines...
Any ideas are appreciated!

Thanks!
