Think of the rooms near your sewing room, where boxes can be dumped and you can snag them easily (as opposed to the basement or garage, where they will be opened by someone else). I've gotten a lot of mileage out of "old linens" and "bedding," myself. Plus, there's always stuff like "blue bedroom," too. I doubt that will be the first place your husband wants to unpack.
If you still have kids at home, there are definite possibilities, too. My kids always loved a good conspiracy.
