Stretchy stuff

We've been spending our holiday weekend getting settled in our new house. Our goal is to get as many (if not all) of the boxes unpacked this weekend. When we first moved into this house, we were thinking we wouldn't be able to fill it right off the bat with just the stuff we had. But somehow our stuff has stretched. For example, we used to have a little tiny hallway closet where we stored all of our coat and winter jackets. They all fit in there comfortably. Now, we have a much more spacious hallway closet where there is a lot more storage space, yet the same jackets now fill this closet entirely. How is that possible?
