I think that you are a bit too close to the project and that it is fine as is. Sure, in a perfect world maybe you could take out one of the polka dots (hoping that is the two next to each other that you see!) and switch it with the center, but I read it perfectly clear for what it is, and that the love shines through.
I talk about randomness and aesthetic randomness, true randomness does result in the same fabrics touching and sometimes it results in ugly and generally we are looking for aesthetic/attractive.
Maybe just like your friend and you, the two alike fabrics are supposed to be together!
