2 Matrons of honor?

It should be about what you want, but maybe let your sister know first so you dont surprise her. Your future SIL will be part of the planning anyway, and its pressure off your sister. Just make sure your sister gets to stand in that #1 spot 👌

It sounds like you want her to be MOH to help you with your wedding. That’s the wrong reason to ask someone. They aren’t obligated to and I wouldn’t expect them to. It’s your wedding not theirs. I would be insulted if I was asked based on those reasons. If you want here strictly because you’re very close to her then that’s a different reason but how you explained her made it seem otherwise.

I don’t see why you would need two moh especially if you are just asking your sil because she is creative. I’m sure regardless of her title she will help you if you ask.

I would make your sister your MOH and your FSIL a BM to avoid hurting your sister's feelings. That way your FSIL is still a part of your day but you aren't taking any honor away from your sister.

I'm sure your FSIL will help with planning regardless of her official role.

Just bc fsil is creative doesn’t mean she needs to be a moh. She can just be a BM and you can ask her for help or opinions. Don’t take that special title away from your sister

My bridesmaids help my MOH all the time. They are all eager to be a part of something and give their input when I ask. I think you sis should have her own title and SIL can be a BM if you really want her to be apart of it.

I have 2 matrons & maidens.... do what you want it’s your wedding.
