You may want to think of it in another way. Instead of "hiding" it and then packing it when you move. Pack it now and save yourself a step.
In general a de-cluttered house will sell faster and for a higher price. If you don't need a fast sale or aren't really concerned about the actual sale price, letting it look "lived in" is perfectly acceptable.
I know when I was looking I would not really consider a packed or untidy house.
