I really haven't involved my FMIL at all...this thread has me thinking maybe I should. Although, it's pretty difficult since she lives in another province. I did send her pics of my dress and my MOHs dress...so maybe that's enough. I don't really need her to do anything..I've handled everything pretty much myself. My mom & MOH both live out of province also so I've been communicating ideas & pictures with them through email, but I didn't really think to include FMIL with all these details. She just went through her daughters wedding, so it's not like she's never done it before!! I think I'll just let her sit back & relax & enjoy the show!!
But if you are getting the feeling that she wants to be involved give her a DIY project to handle, or ask her to keep an eye out for this or that when she is out.
