How to make each of my maid/matrons of honor feel special/honored on the day?

Are these three the only ones in your bridal party? I understand having two MOH's, but every single person in your bridal party being a MOH kind of defeats the purpose to me and does make it feel less special. Regardless, you're asking your friends to stand with you on one of the biggest days of your life, that's an honor. I don't think you need to do anything extra to make them feel special.

Yes they are the only three in my wedding party. I know it sounds like I couldnt make a decision but each of these girls brings something special to me with planning, support etc. and I couldn't stand choosing just one or two. Do I instead not have any MOH's and have them all be Bridesmaids?

That makes more sense to me, but that's your decision to make!

I would have them all as bridesmaids, personally!

I had 3 bridesmaids and no MOH. As for making them feel special, I paid for their accommodations for Friday and Saturday night, paid for their makeup if they wanted it, fed them breakfast and lunch on the day of the wedding (we also had a welcome dinner and a farewell brunch the day before and after for all our guests), gave them quality gifts (real diamond and pearl gold jewelry among other things), and made sure each of them felt included in some special way. I asked them if any of them wanted to give a toast and let them decide who that would be. Another one helped me in my dress. Another one helped with my veil. I took pictures with each of them individually. Overall, I just made sure that I spent a little time with each of them that weekend.

I'd also go with all bridesmaids instead of all MOHs, wondering if that's what I should've done from the get go. I only have three girls too and I couldn't choose between my two sisters so I'm having one maid of honor, one matron of honor, and one bridesmaid (FSIL).

To me it doesn't really matter what you call them -- especially since it's just the three of them in your bridal party. I think it's more about how you treat them and that they each know how incredibly important they are to you. I think it's awesome that you recognize how lucky you are to have three such special people in your life and it's wonderful that you want to honor them all. Daughter had both a maid and a matron of honor; the matron stood next to her at the ceremony and held her bouquet and the maid signed the marriage certificate as a witness. I'm not sure what else there is for a third, but maybe a reading? Daughter's two honor attendants gave a joint toast (and one of them, not the one she expected, became so emotional that the other had to take over and deliver their planned message). Congrats on having such wonderful women in your life -- that probably means you, too, are an incredible sister & friend!
