Activity for Angela

Ok so I'm stuck idk really what my theme is but I do know that my main color is wisteria(light purple) and I want to incorporate sunflowers into the theme ( my FH dad who is passed loved sunflowers) but I don't want people walking into the venue...

So long story short me and my brother don't see eye to eye on alot of things but I've always wanted him in my wedding dreamt with him in it. But 2 things my fiance and him are not close at all and my brother didn't ask him to be in his wedding last...
