With covers you need to be careful how with what you do to represent your story(ies). 

You want to make sure you're properly expressing what your story is about without giving everything away. You want it to be appealing, but also contain enough mystery it pulls in readers.

On Pinterest, I have a board just for my covers. 

Now I'm not making a new cover every single day, so this isn't a board that I go to very often. Once in a blue moon, I go in there looking to see if I have something I'm interested in using for a new story.

It's very useful and I know that it's there in case I want to save it to potentially use it later.

I also have a section on the board to keep my used covers. I don't really know why other than lately in the past couple of months I've been working to move my works onto AO3 just as a backup of sorts. A couple of months ago there was a big scare that there were some people hacking into Wattpad accounts and deleting the stories, and it scared me that I would lose all of the stories that you and I love so much. 

I stopped stressing over it after a while, but I am still in the process of grammar-checking and transferring my stories over there. 

1. To spread my stories further.

2. Have a back up incase something does happen to my account/stories.
