FI has two nieces - they're 14+15, so too old to be flower girls, and I don't want to give them crap "jobs" like guestbook attendants - 
Anyone have any ideas on how we can involve them in our wedding? 
FWIW, we're having an interfaith, but mostly Jewish, wedding. 
I did make two little ring dishes, and I thought about having them bring our rings up front at the appropriate time (sort of like ring bearers, but not processing down the aisle). 
Thoughts?
