i need help…

I'm building a decently sized base in my Minecraft world. This large room will be my bedroom although I need help decorating it. There's a few design elements that I want to be included such as my bed in the center back and I want mirrors to frame my bed. Problem is, I don't know how to make good-looking mirrors that aren't out of banners. I also need decoration and storage in my room, but I don't know how to incorporate that. Can anyone help?
