I’m trying to be grown and recently purchased a Queen anthropology duvet cover! It is a button closure. I am trying to find an insert that is button as well but I’m not having luck. I have checked target, Walmart, bed bath and beyond, quince, Casper, anthro, crate&barrel. If I have buttons do I need button closure or is there another way to secure without buttons?? I don’t really want it free floating in there. I’m also trying to not spend a lot of money but I’m desperate at this point and just want to use my new bedding!!
