Last night I told my husband that I was going out to get Roman shades for the living room. I'm sure he has no idea what Roman shades are. He also left, and by the time he got home, I had installed the shades and fallen asleep.
He stopped in at home today during his work break and asked if I'd gotten the shade I was looking for. I had to point him to the 110" wide window in the room where he watched TV last night.
And this is the guy who will argue about any decorating or remodeling decision if given the chance. So I just do what I want, and wait for him to notice (or not!).
