Grandmothers in wedding - special role?

They smile and look pretty just like everyone else walking down the aisle. If you want to give them a special role they can pass out programs, attend the guest book, or be a reader during the ceremony.

I am extremely close to my grandmother on my mom's side so I asked her to be a reader. My grandmother on my dad's side was just a guest. I did however ask both if they wanted to get ready with me. Only my grandmother on my mom's side did. My other grandmother didn't want to arrive that early and thought the cost for hair and makeup was too much. My husband's grandparents are deceased.

You could do a Rose Ceremony for your Grandparents. Have your officiant explain your gratitude towards your Grandparents, then you hand them a rose symbolically. There's a lot of information about Rose Presentment on the internet.
