How do you properly store autographs that arent going to be professionally slabbed for a while?

Being an obvious newbie to TTM autographs I have a question (not my first and wont be my last). How are autographs that are not professionally slabbed yet supposed to be stored? Toploader? Toploader and penny sleeve? Card Saver I? Card Saver i and penny sleeve? Other? I don't want to ruin the signature by storing it improperly.
Thanks in advance.

We're going to get some long shelves and put them all down in our finished basement over on my side near the bar for display in the near future.
