Gift for Bride

They could do the classic something old, something new, something borrowed, something blue. Each brother could get her something and you could lend her something for the borrowed part.

Or maybe a photo collection type thing with all 4 of them together as kids and then a current photo of them together?

How sweet!!

Have you talked to the brothers? What do they want to do? Maybe they have stories from childhood or something that would fit with the "something old, something borrowed, something new, something blue"?

Maybe a bracelet that she can wear or attach to the ring bearer pillow.
Maybe a necklace?

Maybe they can write stories of growing up and how their sister is all grown up? Include pictures and make it like a memory book so she can start creating her own memories with her new life!

I hope someone gives you the "spark" to make this happen!!

Ask the 3 brothers, for an idea.
I mean, that is their, sister, right?
I would think they'd want to directly, do something for her as a "gift."
Giving "toasts" is not a "wedding gift."
I think, the brothers themselves, should be gifting their sister. If it comes from "you"... it is not from them.

As far as "keepsakes"... maybe a personalized pendant/necklace. Like from Etsy.

Just do a search with something like "personalized bride gifts" etc.
Or something like this:

I would make up a bride's wedding day "survival kit" to be given in advance-include a gorgeous framed photo of the brothers/the brothers with their sister

Could you ask them to give you the texts of all the toasts? Then, print them out in a pretty font, on nice paper, and make a mini scrapbook for her. Include some childhood pictures of them all, like someone suggested.

I'm totally confused...are these all adults? Why would you be giving a gift on behalf of someone else? They can give their own gifts, and so can you.
