Single Friends in the Hem

I am having the names of my single girlfriends sewn into the hem of my wedding gown. It is supposed to bring them luck in love. One of my single friends is a bit older than the rest and tends to be VERY sensitive about her single status. I don't want to insult her by asking if she'd like to be included... and I don't want to insult her by not asking her. It will come up during the wedding because the girls I have asked are VERY excited about it and I plan on having a pic taken with them while holding up my hem...

How should I approach it.. or should I not bother?

That is such a GREAT Idea!! I LOVE IT!
As for your friend (sensitive one) I would definately ask her and talk to her about it (but gently just in case she is sensitive) she will probably not want to feel left out...

Good Luck!
