Update: Honestly I havent had time to even bring it up with the bride but we still have 2.5 months
. I really like the hankerchief idea, its a small discrete gesture and she can choose how or if to use it. The wedding that lyssard is in, is for my friend's little diamond sister, I was thinking it would be real cute if they had a family tradition but I think these two diamond sisters have lost touch. Let me know if you have any more ideas!
