Bronte1985's is spot on. Only, I would echo the need to reconnect with recommenders - if you are still near them, there is a chance they might have an opportunity for you to participate in a project, which would build your CV. Likewise, I would look at volunteer opportunities at a local museum or school. Again, as Bronte notes, this is not going to be a determining factor in your acceptance, unlike a strong SOP and WS, but joining in the community in such a way would provide you with "real life" environments (although, don't bank on getting paid) and showcase your enthusiasm in contributing to the community in which your field is apart of.
